for some reason as soon as i play black ops 2 i get signed out of live and im no longer able to play. but i can sign onto my brothers account and have no issue. just another thing i dont understand about xbox live. i says i am unable to connect. so if anyone has any answers as to why this randomly happens out of the blue. it would be awesome for some sort of explanation. i dont even care if it works again. im beyond that. i would just like to simple know why. thats how frustrated i am. becasue xbox live seems to continue a trend of small unexplanable issues like this.
