Howdy,
I’ve semi-fixed my previous issue with the adding games to accounts, its really a gamble when trying to add games. Anyway, I’ve created a new OFFLINE xbox 360 account, I’ve launched Halo: Reach on it and have bought something from the armoury, backed out and loaded the account on my computer with horizon. After adding the previous Halos to my account, I’ve tried to unlock all of the avatar rewards, every other game works except for Halo: Reach, which is weird because I have the physical disc and the others I dont. This is the error that keeps coming up on multiple of the accounts I’ve
created.
