Hi,
 
I have Platinum Producer, and when I try to open a project that was created in X2, Sonar hangs, even when I click "Skip All."
Any ideas on how to troubleshoot this problem?
 
Thanks,
Jonathan

Try loading from the file menu. Skip or disable the start screen. Vastman and myself have the same problem.

Take a look at his thread: Reinstalling Platinum.

HTH,
Brian

Brian - I don't see where your link to that other thread is actually present in your post.

Bob,
Because is wasn't! 
 

I spoke to Cakewalk support and they helped me solve the problem, so I'm posting the solution here in case anyone runs into a similar issue.
What I did was to open the project file in safe mode by holding down the shift key. 
When you do that, Sonar prompts you before loading each resource in the project, and you can figure out which one is missing.
