Um, go into settings, multiplayer, and then make sure the key is off, this might not work as a key because it's linked to a windows live account, I really doubt that if you used the key than this auction is worth anything
Yes it was just purchased and I used the key to make sure it was valid as I bought it as an opened in store item. So technically it's brand new tested.
How many times has the key been used? I have been burned twice on listia because the Key is worthless if they have been installed multiple times. There is absolutely no way to fix this problem.
does it work and what requirments in the comuter do u need like what processor and windows 7 ,windows vista or ,windows XP,and what graphics card do u need
