[Solved] New problem with old Sonar x1. Do I need to upgrade?

Hi everyone.  I'm new here, so I apologise for my lack of knowledge, and any other bads I am going to commit trying this forum thingy!
 
I have been using Sonar x1 Producer happily for several years, and just last week it decides it won't export, import or open a project from the file menu.  I have to get Task Manager to shut it down.  I am in the middle of a project so I need a fix.  The project is very simple - 3 softsynth tracks successfully bounced down to 1 audio. The project still opens from the quickstart menu, and I can work in it still, just not export it.
My computer is Windows 7 64 bit.
I updated Java around the same time as this problem occurred, so have uninstalled that update but am still having the problem.
 
Is Sonar x1 just too old now?  Any suggestions to the cause of the problem?
 
How do I know if I upgrade Sonar that I won't have the same problem anyway to due a computer issue that I can't figure out, rather than anything else?  Because the demo doesn't export I can't tell!
 
I mostly use the True Pianos synth, which is only available on Platinum.  If I upgrade to Sonar Artist can I just load that synth from X1?
 
I appreciate any help and advice anyone can offer.  Thankyou :) 

You could try a re-install Sometimes things just get screwed up and a reinstall fixes what got screwed up

Wow! Hello everyone and thankyou for your replies to date :)  So....
 
When I have bounced my mix to audio, I select the audio track, click File>Export>Audio and it's game over.  The menus grey out and I get no response from clicking on anything.  There is no message. Track Manager tells me the program is waiting on a response from me (as it would be had the dialogue box shown up).  I get this same problem with new tracks and th others I can load from the quickstart menu.  I can't load old ones from File>Open.
 
I have uninstalled and reinstalled several times, installed X1C and X1D, checked the location of all my folders, I tried running the program in safe mode but I don't think I did it properly because nothing seemed any different.
 
I have 248 GB free hard disk space and 6 GB Ram.
 
I'm not sure when I ran Windows updates.  I can check and do that.
 
Thanks again all :)

I never thought of that!  I have a look now!

You may have to reinstall. In fact that is what I would do. 

Try a virus scan. See if you picked up one. Then if that is not the case back your data for a reformat and a full reinstall of the OS. Only do that when you know you have all your important data backed up. This includes all email and all licenses. Don't forget the Windows key.   
 
Lets us know how you come out. I hope its a simple problem and you don't have to do the OS reinstall. That should be your last resort. Good luck!

...I previously couldn't check for a hiding dialogue box because the minimize button is also unresponsive...

 
Minimize won't work on the main window until the dialog box is cleared (assuming that the dialog box is part of Sonar). To access the hidden dialog box, either right-click on the Sonar Taskbar icon or launch Task Manager.

On the other hand, some of your description seems to suggest that your problem stems from something else other than a hidden dialog box. Still worth checking though.

I went to try the "right-click" option you mentioned Kev, but didn't get the opportunity.  As soon as I hit export the program froze and all the error messages came up again. Then the program got shut down.  My preious method after the program froze, before I started getting error messages, was to use Task Manager to shut it down.  That was effective, but gave me clue to the problem.
 
I have done a virus scan and didn't come up with anything.  I am being told that my Firewall is turned off but it wont let me turn it on.  I also cant seem to disconnect from the internet!  I have a lot of learning to do.

Thankyou promidi. 
 
I will look into those things as best I can, and possibly get some IT help after that.
 
What a pain!

Still trying to work out whether this is a specific project issue or not? Issues with new projects? If it isnt def run windows update, run chkdsk /R (google for details) then reinstall.Thx.

For further reference for anyone else, I ended up reformatting the hard drive and doing a fresh installation of my Windows 7. Sonar is working like a charm again.
 
Before I got to that point I installed Sonar onto a couple of different laptops.  It worked ok, so my computer was definitely the problem. 
 
Thanks everyone for your advice.

Happy Tracking !!!
