What is VirtualStore? it sounds like some obscure Vista technology?
The graphic card is updated, SA behaves the same on the two latest versions of cataltyst driver installed i have tested
I have used "Registry Mechanics" long time, its supposed to be world leading..i have personaly never seen that the program fixes will stopp installed programs from working after, but it could be as you say, thats why i allready have restore-backuped every change Registry mechanics have caused during these 2 months, but who knows how believable their backup function works in the reality, theres nothing moore i can do there however, (un)fortentley i dont use Windows restore points either so i cant go that way either
So if i really wanna play SA right now, then i must reinstall windows in my situation ;)or..
