okay so ive had the game since march or april (i forget) but both discs are in perfect condition. i only play multiplayer and as many of you know you need a code to play the multiplayer, limiting it to one gamertag. i cant play mass effect 3 on this profile. neither disc.the game simply freezes after the bioware loading screen. however, i can play it on ANY other profile. and i can play any other game on the profile in question. and if i try to sign in as another gamertag, get to the start screen, and sign into the profile, the game freezes. please help me i dont want to start multiplayer from scratch,.
