I am having a major problem with Sonar crashing on start-up. I have Sonar Expanded updated to d. Earlier today no problems, now I have this issue. I can open Sonar no problems. But, when I open a project here comes the crash. After that I cannot restart Sonar. I cannot manually stop Sonar through task manager. I have to restart the PC. OK, I am using Win 7 32-bit. I have a few plugs that are third party. (Addictive Drums, Focusrite Midnite Suite, and Organized Trio. I suppose this could be where I need to look. I still have the "Floating" demo song installed. That will open fine. Whenever I try to open one of my projects it's a no go. I did check a crash report. This is what it says, copy and pasted below. Description: A problem caused this program to stop interacting with Windows.

And, what is my next step? Any help would be appreciated.
