I have both Noble 1 and Defiant map packs downloaded, without any issues. Whenever I try to go into multiplayer matchmaking, the game says that I have “Content Missing: You are missing recommended downloadable content. Would you like to visit the XBOX Live Marketplace to learn more?”
If I say “Yes, take me to XBOX live Marketplace!”, the menu indicates that the Defiant Map pack and the Noble 1 map pack have not been downloaded.
If I download them through this menu, I can only download one, it instantly finished the download, asks me to select a storage device, goes back to the matchmaking menu, and the game will say “One or more players do not have the maps required to play in this playlist”.
I have tried deleting the map packs from my hard drive and reinstalling them from the XBOX dashboard.
