Problem with activation key.

Where did u buy the game? what version is it? If you can use steam try to register your gamespy cd key with steam and then steam will reinstall game for u and download it and auto patch it. If you unwilling or cant then uninstall game make sure all the files are gone manually and also mowas folder under my documents\mygames\ as well reinstall game and then apply patch right away.
