When i go to get onto Rock Band 2 for X-Box live on my 360 it says, "In order to play on X-Box live you need to be signed into an X-Box live enabled gamer profile with X-Box live Multiplayer privileges enabled with X-Box Live"
I have a X-Box live membership and as far as i know the multiplayer is enabled. I have played Halo Reach and other games on X-Box live so i am confused as to why its not letting me play this on live.
