SONAR X3 hangs or doesn't even start

Hello everyone,
 
my name is Steffen, I am new here, this is my first post and I hope I do everything okay.
I am here because I am having major problems with my SONAR X3. Basically I can't work with it anymore because it either hangs or doesn't even start anymore.
It began a few months ago when it would more and more often just stop responding while I was working with it. If that happens I have to force SONAR to shut down. After such a hang and shut down the Audio driver is somewhat lost so that I have to restart the computer to get it back to normal.
 
That used to happen about once every hour or every two hours.
Then during the last few days or weeks it got worse and SONAR would often hang right from the start, immediately after opening a project, as soon as I made a first click anywhere. With that I often had to start and restart my computer a few time before I would finally get it to work.
 
And now yesterday I had again been going through different loops of starts and restarts and just wanted to try things and find solutions when I changed the driver setting from ASIO to WASAPI.
This caused another hang and made it all even worse because after that SONAR wouldn't even open a project anymore. It starts hanging when I click a project to open it. Afterwards, after shutting it down again it is not even possible to start SONAR at all.
 
So this is where I am standing now. I can't work with it at all and I am desperately searching for a fix.
I suppose this won't be done with a single step:
I will have to get it to start somehow to switch back to ASIO as this seems to have added to my problems. Then I will need to find out where the culprit lies, most probably I have to go through the different plugins and check if something is wrong with some of them.
 
So what I am planning is to start it in save mode (with SHIFT clicked) and then get into the settings. If this doesn't work I could try to open the AUD.ini file (which is the configuration file as I was told) and rename it or set it back to a previous state. Possibly this could be like a fresh start with settings back to standard (not sure, but hopefully it is!?).  Finally if none of that works I could set my whole operating system back to a previous state.
 
Please tell me what you think about my plans?
Has anyone had similiar problems before and found a solutions?
Any hints where such problems like occasional hangs do come from? I have a pretty fresh system with no other programs on it except for different VST plugins? 
Are plugins the typical cause for such problems and how can I go about it? Is there anything better that just deactivating all and then turn them on one by one, see what happens and hope to sort out the bad ones? Wouldn't it be possible to set up a save list of plugins that work. 
 
In short, you see I am having a problem here. So throw everything at me that could be of help. I am grateful for any kind of advice or hint.  
 
Thanks,
Steffen

Just to confirm are you running the latest version of X3 - I think it revision e.

I tend to agree with robert on this one. In addition to searching for errant plugins, bump up the buffers in preferences, to give your processor and sound card a little "breathing room". If you have it set to a fairly low level( 64 or 32) try 128 or 256. You'll get some noticeable latency at those settings, but at least it should start up without immediately hanging up. That will give you a chance to fine tune our system a little more.

It looks like you have tagged this as answered so hopefully all is good now. 

I don't know. I didn't do anything, at least not consciously tag it as answered. So, I don't know, must have accidentially clicked somewhere.
BUT: It doesn't look so bad, see my replay to Bob.
 
Edit:
Now I figured where that "Answered" tag comes from. I replied to Dave's comment and clicked on "answer" thinking it meant I would directly respond that way. I corrected that now. 

Well, that IS good news - if it holds up that this has resolved your issues.
 
Please continue to test, and post back in a bit with either a confirmation that you are a happy camper now, or give and update with whatever new info you may have that we can use to dig in deeper to try to get things resolved for you.
 
I am personally rooting for things holding up in continued testing - meaning that this is resolved for you.
 
Fingers and toes crossed on your behalf, 
 
Bob Bone

I checked my buffer settings. I think they should be okay and not too low. Would anyone disagree or find some fault with the following?
 
I checked at Preferences > Audio > Drivers and clicked "ASIO-Panel..." which opened another window called "Line6 Audio-Midi Devices" with the following settings:
--------------------------------------
ASIO Client:
Default Buffer Size: 512
Default Bit Depth: 16 bit
----------------------------------------
and then there is a slider with my mark (^) somewhere between "Extra Small" and "Medium" with no numbered values
----------------------------------------------------
Buffer Size:
| Extra Small |    | Medium |    | Extra Large |
                   ^       
------------------------------------------------------

Okay, I had another freeze/hang.
I was working with SONAR for an hour or little more with no obvious limitation when suddenly the teleport server error message popped up  (translation would be something like "The Teleport Server doesn't function anymore. The program is not working properly because of a problem..."). 
Playback stopped and SONAR stopped responding. I could still click here and there but there was no reaction and then the next error message appeared with something like "SONAR doesn't respond..."
So after a couple of minutes I had to shut it down like I always do with a click on "X" and a little waiting.
 
Starting SONAR again I got the same next error message as before "no audio devices for the current drivers connected to your system" and when I opened SONAR and went to preferences I could confirm that the fields were empty at
preferences > audio > devices and
preferences > audio > driver timing-master playback / recording
 
When this happened I was playing around with a plugin called 5orcery which didn't seem to cause any problems so far.
 
* So is this something worth searching for a cause or is one crash per hours just a normal number one has to be prepared for?
* And, is there anything I can do to fix the "no audio devices..." problem except for restarting the computer (which is what I now always do)?
 

Thanks Anderton. I must admit I didn't know what the teleport server stands for.
So it needs some kind of technology to make 32bit plugins work in a 64bit system. SONAR uses BitBridge to do that. The teleport server is some part of that and a teleport error message indicates that there was a problem with a 32bit plugin. Would that be correct, in its very simplified form?
I must admit I still have plenty of old 32bit plugins so this could be something I should put an eye on.
