IWork crashes after OSX Lion update.

Question

I recently updated to OSX Lion, and after that I installed all the software updates that came with the software installed. After the migration to OSX Lion all the iWork programs stopped working (Pages, Keynote, Numbers). I already re-installed the iWork suite, and replaced the framework folder from the error message below with a backup from Time Machine... but the error remains. Can somebody please help me?
