CD KEY NOT WORKING?
CALL
Games for Windows: (800) 537-8324
not sure if that number still works etc, but it is from the microsoft website lol
and****
the keys for Halo 2 Vista and the listed games below all work for each game. so if you want to use battlestations key for halo 2, it will work for halo 2. The games are the old key system micorosft used. The keys that are out now after i think 2010-2011 are registered for one game and one game only and tied to one account that activates the game with the key.
But anyways if you find a game thats new and its listed below their key can work for halo 2 vista. I think it should still work lol*
