me and my housemate both got COD 5, bought it for the co-op feature but everytime we try to play co-op, it says on his machine that " the cd-key is already in use by another computer " 
i bought mine before he bought his, and we installed my copy on his pc to see what it looks like. then, we uninstalled it when he got his copy, installed his copy and all of the sudden we get this problem... we went to the registry folder , but you cant change the cd-key there.. we changed the cd-key in the game aswell, nothing helped...any advice on this matter would be appreciated
