I do experience a strange problam with PE 12.0 . Starting it either aborts with an Appcrash error message or does not start at all whenever I try to open an existing project or when creating a new project. If I leave it alone the organizer starts.
Renaming the prefs-file in C:/Users/ab/AppData/Roaming/Adobe/Premiere Elements/12.0 as has been suggested in another thread did not work.
Any hints what I can do to get a working installation again (apart from reinstalling) ?
