Make sure you select the Hard Drive that you downloaded it on as a save device, not a Memory Card.
Wait a bit in the game itself, and after a while it should pop up, it takes a while to recognize that you have them.
Make sure you downloaded it linked to the gamertag you bought it with.

If all else fails try Bungie.net
