Not sure if this is the right place, but here goes.
My brother recently moved close to me. We have been going back and forth from here to his house and playing xbox games together. I put my profile onto a memory stick to easily use my gamesaves etc. Well, while I was home playing Bastion today I realized the games and achievements I had earned at his house weren't in the list. He doesn't have internet hooked up yet at his new place, but I was wondering is all that work lost? I 'think' my total gamerscore has risen, but I don't see any of the games that are responsible for this in my games played list. How can I fix this short of bringing all his disks over here and loading em up one by one? Also, if I am correct that my gamerscore is higher, then the gamerscore in the list versus total don't match up. Even though I doubt anyone would notice that to start with, I don't want people getting the wrong idea and reporting me for tampering or whatever.
Also I tried recovering my account, but that doesn't fix anything as the website doesn't even show the achievements/games. Also I thought it may have to do with the update that came out the other day so he installed the latest from a usb stick and it still has the problem. Another thing, his is the original 360 and mine is slim. Although this should be software related I thought I would mention it in case it's of any relevance.
