I just tried to redeem my blimp add on code and it says its already been used, but obviously since I just got it, it shouldn't be.. Does anyone know how to fix this?
Same thing happened to me, I bought a 1 year Xbox LIVE code form amazon, and it had already been used, apparently Microsoft can't do anything about it!
contact R* support and maybe they can hook you up with a code.
Don't worry blimp isn't that great anyway, only thing you can do is contact support.
I just redeemed my code using my computer and had no problem. Just curious, did you enter your code via the xbox console or a computer ? I realize it shouldn't make any difference, but stranger things have happened.
