HELP DOWNLOADING WAR GAMES MAP PASS?

Hello all,

Just lookin for some wise words of wisdom. The war games map pass was sent out today for all those who preordered the limited edition of halo 4. I entered my code, and downloaded it, but it didnt register on my xbox as me having it. So i deleted it from my hard drive and attempted to redownload it. When i re entered the 25 digit code, it said that the code has already been used. What do i do? Its not showing up in my download history either

I would check to see if you have your specializations or check back on December 10th to see if the maps are ready for download. if not you should probably contact xbox live support or if worse comes to worse buy a new map pass.
