this happened to me twice, i logged on battlenet and made a game, and like a few seconds later i got a connection interrupted and then i got realm down and i couldnt play till like a while later and when i got back on it did the same thing......
Then dont play. Everyone who bitches about stuff like this sounds like a little kid to me:
You put your hand on the stove "OHH! THAT HURTS!" and do it again.
If you like playing the game keep playing regardless, if the game isnt worth the problems B-Net is having then stop playing for a few days and try again.
Grrrrrr.
Maybe tonight we'll fly so far away... We'll be lost before the dawn...
