I've had Windows XP Pro Installed on this particular problem machine for about 6 or 7 months now. Last night, the power went out with the computer on, when I rebooted the computer, and when I click on my name in the windows welcome screen, I get a message saying my computer needs to be activated, but I vividly remember activating it, ummmm... like the day I installed Windows. When I click, activate now, the next box says that Windows has already been activated??? I click ok, and it logs me off... and that's all I can do.
So now what am I supposed to do? How do I re-activate my copy of windows??
