My advice: let it go Martin. I got as advice to update my videodrivers. Yeah right. From catalyst 13.1 to 13.2 for an old radeon 7950. That'll do the trick. I'm not even going to try because i have to do a complete system restore to get my computer running again.
Stardock has gone over to the dark side, so from now on all updates are windows 7 backwards compatible as luck will have it.
