I bought black ops 2 in the United States before moving back to France, opened it in France, and was surprised to see I had the Nuketown 2025 DLC code. I decided to redeem it about a month after i got it, and saw the code was invalid. I hear it might be because I bought it in a different country, and since I have a French PSN account (I live in France) the DLC code does not work.
What should I do to have the Multiplayer and Zombie map ? Thanks for reading.
