bought a new xbox 360, the halo 4 version, aqnd transfered my old xbox live profile to it. but i dont have all my game memeory, except for halo 4, which i dont know why, and all my achievements from every game, but bot the game memory itself. i also dont have any of my DLC's or avatar items. do i have to re-beat all my games, and re-download all my content pice by pice or is threre a faster way? any help would be appreciated.
