Xbox 360 Slim and i save it to the hard drive. I play social slayer if that's what you mean by types of games. Plus it shows ive played like 50 games or whatever but no xp gain. i also have been playing for 3 days so it shouldnt have happened or might have happened earlier

recently i bought halo 3. got to the rank of private and then had to move my xbox somewhere else. i signed in again and my rank was back to recruit. i played 25 rounds and i have not gotten any xp..... Help me plzzzzz!!!!!
