Same here. Win7 x64 is working just fine for me. Screw M$.
“Screw M$.”
I was screwed by M$ is my take on it.
I had two perfectly good Win XP machines, that Billy Gatsey locked me out of. Had to make minor hardware change to machines and XP sensed it, wanted re-authorization to occur, servers gone, machines locked up 3 days later, end of story.
No way to get back.
