client errors

Ive been getting client errors pritty regular. Last night I was playing downtown matchs. I was trying to get the 45 kills needed for daily mission. I played 6 games 5 of the 6 games i client error out after the 6th round. The last time i client error was at the end of the last game i played litteraly 12th round bomb defuseing end game. I was 35 kills in. all i did was turn towards the guy defuseing the bomb and bang client error. I stop plaing for the night at this point.
