So i bought my xbox about 3months ago, and it went jiggered.. fair enough, got it repaired.. not best pleased but these things happen. but now i cant play online on some games that require a registration code for the online features to be accessed. i cant reuse the codes i got when i purchased the game, it says this code has already been redeemed. please enter an unused code. So how can i get back online on my games, without obviously, paying again to access features that ive already paid for?
