X box live membership

Hi, I've just purchased a 12 month gold membership for my son. I accessed the code and activated it without problem, but when we try to log in on the Xbox it says that the email is already associated with another account. We tried to access 'account' in
settings but it is not available to click on. I really am at a loss with what to do and would really appreciate some advice please. Thanks.

Rock Band 2 X-Box live no work

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.
