Xbox 360 lives ran out!!

Well I just ran out of live, Call of duty 5 I was playing. Am a level 57 general in 2 prestige. I was online heading to a team match with my friends until my live file said it has run out of live. I was really disapointed to hear that. All my friends were wandering why I wasn't in the match. During the weekend or friday, am hoping to go to gamestop for more live. If this I cannot buy live during this week, I have nothing to do then. Bored bored bored, all week I have no skate location and no ride. either stay home do nothing. If anyone is on the internet on there home computer, lets play a computer game online.
