I purchaced the limited edition of halo 4 and downloaded all the content to my hard drive. I used the codes for all the extras and things were going great. My hard drive was filled up to the max with games so i transferred Halo 4 to my flash drive. when I went back into the game, all my extra content (Weapon Skins, Forest Armor, Emblems. EVERYTHING) was gone! How do I get this back?
