the other day, I tried to download the 2 new maps, after a short time, i found out that i need to attach a credit card to my account so that i could be billed the $4 for the game. However when i went to the content download for the maps again, the bar started at the very beginning, then shot all the way up. After this I was sent to a screen that said, "content download failed, please see www.xbox.com for help". I couldnt find anything to help me on xbox.com, so i figured it must be something wrong with my modem, i pushed the reset button on my modem and on my router. After this the same thing occured on the download menu that had before. I thought that something could be wrong with my hard drive, so wiped it clean of all game memory. Now, it still wont download the new maps, and now it even wont download the maptacular map pack( containing-terminal, backwash, ect.). I am at a loss, the content download page even says below the download for Tombstone and Desolation that they have been purchased. Does anyone know what I can do to fix this problem, I have tried everything I can think of.
