The correct term is not that DVDFab (newest version) crashes or closes. It is that half way through the "opening" tab, it just goes away. I thought perhaps there was a conflict somewhere between the last version and the new one that was downloaded last night, but that is not it either.
At least with removing the old version and re-installing the newest version (again) the progress went a little further, but with the same result ultimately.
Any other suggestions, other than "copy just the main movie" that I have ran across?
