imovie keeps crashing - even after deleting the (only) preference file

I'm using imovie 11 version 8.0.8 on OS X 10.8.2 on an imac. iMovie keeps crashing especially when adding titles to a project.

I searched for a solution and found several sources that indicate to delete the three imovie related files in the library/preferences folder (which is now hidden). however when I go to that folder i only find one of the imovie files, the one called: com.apple.iMovieApp.plist. There are supposed to be two other com.apple.imove.xxx files.

I delete the com.apple.iMovieApp.plist file, then restart imovie, but this does not solve the problem.

Can someone help? What else could I try?

I've already checked for software updates and I'm running on the latest.

Thank you.
