[Cihparg]

Greetings, could someone tell, what the hawk is up with mah battle.net?
I've checked my firewall - So it's not that.
It shouldn't be the router.

But, If you know what is causing this error, please tell.

So like I told you on msn:
I'd suggest you check out the Blizzard support and if needed e-mail them about your issue.
