do a search for the license migration tool. this will solve your headaches. basically, the content is locked to the original console (and the purchasing gamertag), and just needs to be migrated to your new system that came back from repair.
basically, you will go to a special option on your dashboard and redownload the content and update the licenses (instead of just re-downloading from the marketplace)
on a side note the un won't solve any problems for anyone, they're obsolete and useless This post has been edited by Reaper527: Jul 28 2008, 10:15 PM
