Everything is set...I have been playing Halo 3 with the same router, same settings since the day it came out. I have two discs...Halo 3 and ODST multiplayer...it does it on both and only with my gamertag. If you notice, my gamertag wont even sync with my bungie.net account. My gamertag is skeetskurt as well, and my email address is the same as well.
