Hi kpnitrl and welcome to cdfreaks,
Sorry for your trouble.
First off, I don't know beans about Vista...and no love lost there. You'll have to pry XP from my dead, cold, clammy hands.
Anyway, a few ideas...
You may want to consider running a decent registry cleaner. A lot of us recommend Regseeker...there's a link in my sig.
(I think the clean uninstall...below...recommends this as part of the uninstall).
Do a clean uninstall...courtesy of my good friend StormJumper. He has a great guide on complete uninstalls...just look for a post ...there's a link in his sig.
There is also a ton of info put together by zebadee re: Fab and Vista:

Hope this helps...until a Vista freak pops in to lend a hand...
