Just one project refuses to open, just spins round and round and round and...

Try opening the project in safe mode. To open a project in safe mode hold the SHIFT key while opening the project.

 What do you think that this means if it does open in Safe Mode? If you have any ideas on what to do next
 

Opening a project in Safe mode allows you to selectively choose which plugins are enabled for that project.  You can use Safe mode to let you know which plugin is causing the project not to load normally.  Once you have isolated the problem Plugin, you can then save the project (suggest under a different name)

Small update that's not looking good for Sonar-
 
So far, using the safe mode feature pointed out to me by scook, it appears that it is a Sonar x3 plug-in that's causing the problem. I wouldn't think that this could happen but I am now using nothing but Sonar plugs and I still am seeing the problem. It appears not to be the compressor or the EQ thus far, which is good for sure. It would be difficult living without those two!
 
Thanks again for your help

There are many, Many reasons why a project can get stuck in a loop.
If you have managed to open the project in safe mode, you can export, or drag and drop your tracks to a new project. This can eliminate a multitude of issues associated with your software setup, or just the way that particular project is set up in that particular space on your hardware.
If all your other projects are working fine with the same plugins, then it 'may' help to move this project to another place on the HDD and then re setup your plugins. It's kind of akin to doing an old fashioned defrag and has fixed the exact same issue on my computer on more than one occasion.

Hey! Thanks so much all you guys for helping out, I do really appreciate it greatly!!
 
Now, to try to answer some things that you all asked...
 
Noynekker, I have most likely eliminated 3 plugs so far: Compressor, basic EQ (not LP-64), and channel tools. Although I wouldn't completely bet against those 3 just yet.
I am slowly re-adding the plugs and then saving-over and over. I was already developing a creeping feeling about what you suggested: Multi-band and LP-64. I did actually switch to the LP-64 and add the multi-band right about the same time that this irritating problem began. So, I think that you saying this really goes some way toward helping to locate the problem. I will switch back to the basic EQ and dump the multi-band, for now anyway. Hopefully, this is where some or all of the problems lie.
 
Many thanks to you for your help!
 
 
Hey rebel007, thanks for your suggestion too. I was actually also beginning to entertain the exact same thing that you spoke of. It is a fine feeling to hear that someone else has had this same problem and I thank you for coming forth with your story! I have never had these sort of problems before, and this is when I ran Reason concurrently with Sonar, so I was surprised when this began happening. I will be trying what you suggested if this doesn't stop very soon.
 
dwardzala, thanks for you help also. To answer your question, I do not have Platinum, but the one right beneath it-whatever that is called-Pro, I think. I don't really know what that means, to run as admin, I never have known! I just bring up Sonar on my desktop and go from there. This has always worked before this. It is curious about the problems you spoke of though. How would I log in as admin? Do you mean on windows or Sonar? Thanks for your suggestion!
 
Thanks guys, I will try some of this stuff out and be back soon.

Thanks dwardzala, I will give that a try just for fun if I have too! I do use 7 so I will check out the shield.
