with battle.net...every time i leave a custom game or a solo game, i get dissconnected from battle.net or when I am in a channel I will be dissconnected every 5 to 10 minutes.After i am dissconnected,it will tell me that my CD key is in use by 1337 PC( MY COMPUTER). it just started doing this all of a sudden, before I could host with no problem, but then when I would host a custom game i would get dissconnected.Any help?
