I moved into the dorms at the University of Northern Iowa last Thursday...to access any online gaming we were asking to manually send in our box's mac address and they would allow it to connect to xbox live or other online gaming...so i did this and after about a day it connected on the dashboard...i pop in halo 2 and when i get to the menu and click xbl all i ever see is the "start trouble shooter" screen...i have tried resetting my cache and i DO NOT have family settings on (i have asked this around many other forums and all everyone talks about is family settings)...i have even tried recovering my acct...the campus uses Resnet...if anyone else has had this problem and has any comments please share...thanks
other xbox 360 games do work online...i was able to play an entire game of madden 08 on xbl
