i have paid for and downladed all of the map packs for halo 3 but when i try to play most of the game types weather its social or ranked it says one or more players dont have the maps to play this game...but i do!!!! it used to work fine, me and my boyfriend both have profiles on the same xbox, but only i have the maps...this shouldnt make a difference because the maps have been downloaded to the same xbox! i have tried deleteing them all and reinstalling them but still i cant play avalanche or any of the new maps, even though u still get rats nest. I cant seem to sort this problem out can anyone help?????
