ok about 2days ago i baught a 13month xbox live card for $59.99Can. but after the 2 or so days i try to play COD4 and when i try to connect to xbox live nothing works right and either kicks me out of xbox live (back to the menu of COD4) or my whole system just freezes, and i have to restart it. i have a 20gig harddrive and i used other profiles on my xbox and they seem to work, but i cannot get them on xbox live because my 13months is only on my main account that isn't working. please help and tell me what is wrong. thanks you.
