I just got my new 27' 2.8 iMac 
and am trying to install (a used ebay copy) of CoD 4 and when I click to open single player it gives me the message "Not Authorized" same issue with multi-player. Can anyone help me with that?
If this is a misplaced thread or a repeat I apologize in advance and ask to be point in the right direction. Thanks!
