I have reformatted my computer multiple times and have reinstalled windows XP pro on the same computer multiple times without incident. However, now it is telling me that I used my cd key too many times and it is no longer operational. This is ridiculous. I paid for my authentic OEM copy of Windows and they are saying I can't use my CD key. I tried calling the CD Key phone support and the number doesn't seem to work. I don't know where else to go since their support only works with retail versions of Windows. How can I get my CD key to work? I need Windows Updates and DirectX 9.0!
