Trouble with Halo 2 on Live! PLEASE HELP!

Hey,

I just set up my live account yesterday. Anyway, when I sign in to go to XBOX live on Halo 2, it says that I have a message from Microsoft, so it takes me to a menu where I can change options. After about a second there, it goes back to playing Halo, as if it is turning the game on for the first time. It works fine with Gears of War, but I bought my live just to play halo!

Someone Please Help Me!!!

its on family settings on xbl settings on the dashboard thing, u have to change it so u can play regular xbox games on live

yea, its either under network settings on the last blade or under xbox live, im 90% sure its xbl thing so go to the settings n under the family settings or something.
