Need some other people to confirm this also, but worked for me. Requires that you have downloaded the new maps/gow2 content with a xbox that you do not have anymore prior to getting the new one and recovering the GT. I got a new xbox which I had a GT already(My Rank 5 Star acct) and the maps installed on which was the only one I could get host with. I had created two others after the new xbox. These two other acct, i could not get host no matter what, but i could switch to first acct and bridge fine. EXtra: I was also getting the errors, ?Int?Errors.ConnectionLost? when on the two new acct when trying to use the new maps, flashback and bustables. To fix the above error, log into xbox.com with the GT that is associated with the first purchase of the maps, I.E. GT you first played GoW2 with and inserted the codes for, and click on > Support Menu option then > License Transfer. Follow the instructions, its two clicks of a button, real simple. It will direct you when you are done to redownload the content on your new xbox(which takes 1 sec fopr the maps, prolly just updates something). This fixes the above error AND also for me fixed my issue of my new GT not getting host. I succeded in pissing off 4 games of people, and played my first wingman on this new account, winning with 20 points, 14 kills and 4 deaths, leaving me with a 3.5 k/d. Should get my second star soon. Please confirm if this helps anyone on getting host on new accounts. UPDATE: Just tested both of my accounts that I could not get host with, I now can. P.S Also may of found a way to get host by your self. More latter still in beta.
