Both at the same time is stretching coincidence and what made me suggest a windows update or other OS/system change that might effect the way DVDFab behaves. A Java update released last week caused all sorts of problems. Same for XP a couple of weeks ago and Vista is full of its own challenges. Do you have a restore point set that you could go back to without too much pain? Then just install 3.1.1.2 over whatever is there and see what happens. It never comes easy. Maybe somebody else will have an idea.
