When me, my cousin, and his friend play Halo 3, he logs in as his acount, that have Xbox live, and we log in as guests. But, a message appeas saying something about not all the players have xbox live. When he tries it alone with no guests , it lets him play. Help? P.s. My uncle is using the Television, so I can't see the exact error message. But, if it would help, i'll try to get it.
