    is this a product key for the game or the OS??

    If it is for the OS it will have a activate by phone option. Just call the toll free number and tell them what happened. I have yet to have microsoft deny a reactivation.

    (Note: microsoft allows three activations per cd key before this step is required.)

    as that would be a legitimate copy of course... reinstall the game and use the key provided with the cd
