Hello,

What we need to do is to post on their public forums so that our folks from 343 industries can review your concern and once they have confirmed the issue, they should give you a reply. If they say that there issue has been fixed or if there's nothing wrong with the map packs on their servers, please contact us back with your reference number so that we can investigate the issue further.
I purchased Halo 4 limited edition which came with a card with 4 different redeem codes, the first being for the War Games Map Pack -- I redeemed the code long ago on a different Xbox than I am using now.
The game/Marketplace doesn't show me owning the Map Packs -- but when I transfer the license to the new box the packs show up in my download history -- I am able to download them for free (Download Again) but when I boot up the game:
"Unable to Validate. You have Map Pack content that requires a license. Please purchase the War Games Map Pass, purchase the Map Pack individually, or delete the Map Pack content from your console."
Any help would be appreciated.
