I have a problem, I finished The Last of Us around 4 weeks ago, and decided to play Factions. However, when I had tried to put in my code, it said it was invalid. I bought The Last of Us new, at Gamestop. What should I do to report an invalid code? The only reason why I waited so long to put up a post, was that I tried to contact a moderator, but he/she didn't exactly reply. So now, I decided to put up this post to see what I can do about it.
