This is really frustrating.
I have a saved project and I have to keep re-saving it in different forms because every couple of days I get the message "SONARPLT.exe has stopped working correctly. Windows will close the program and notify you if a solution is available."
 
My computer is new, I'm running Platinum as Admin, I have plenty of RAM, system is updated, but still running 8.1. I haven't updated Platinum since July's update.
 
How can I get this project to open? I am sick of having to save my projects 20 different ways and then still having to roll back to a previous version and lose my last bit of work.
 
PS: Now I'm really screwed, because I also saved it as a bundle and I can't open that either!
 
Thanks

I got it to open by opening a previous version, and then opening the later version on top of it.
 
I had a REX file loaded into Dimension pro which was missing when I finally got the project open.  I am going to try to re-load the REX and then Freeze the synth to see if that solves the problem.
 
But the important question remains: Is there a way to get your project open whether it is a glitch, or operator error?? This is especially important to me as I am a new user who is bound to make errors.

Hold the SHIFT key when opening a project. This starts SONAR in safe-mode which can load a project and skip plug-ins.

That sounds like a really handy tip, thank you.
