So I've finished the story campaign and i now want to play online but it's not allowing me to access the code. Trying to redeem the codes from the main menu and it's telling me that this code is already taken? But i'm the first to have own this game. Has my code been stolen? Please any help would be great or where can i take this further?...
Just to check, but does your copy of the game match your PSN account, as DLC and codes are region locked, so only NA codes can be used with a NA account, and so on.
This may be your issue. Please check your game and make sure the region is correct. If you game/online pass indeed matches your PSN accoun'ts region you will need to contact Customer Support about the code here.
