So i just bought the Noble map pack, The Defiant map pack, and used the code for Anniversary map pack from Halo Anniversary. They all downloaded to my hard drive completely. So i started up my Halo Reach and it said that i failed to load content even though it was in my hard drive. I had no problem with the Noble map pack though. So i then went through some forums and they said to re-download it or delete bungie pro. So i re-downloaded both Defiant And Anniversary but nothing. I also looked for the bungie pro and i didn't have it in my hard drive and i cleared the hard drive cache to but still nothing. Any help anyone?
