The type of crash with no report screen has only happened to me in DVD to Mobile if there was a problem with the profiles (missing, corrupt, misnamed etc.) but these should have been re-written when you installed the new version. The one I have tested in Generic worked fine for me (xvid+MP3). Check to see if they are installed where DVDFab expects them to be (C:\Program Files\DVDFab Platinum 3\Profiles). Open the one you are having trouble with in Notepad and see if it seems to be intact. You might also try installing and running the new version with AV and Firewall disabled.
