When i try to log on it doesnt seem to try and authenticate or anythign it just keeps saying DISCONNECTED FROM SERVER and nothing happens.

I have BC installed and am on Patch 2.3.0.

Any ideas?

ya. you are on 2.3.0

and china is not. (hopefully next week).

again, rule of thumb: NEVER USE THE AUTOMATIC patch thing from blizzard. you can download patches manually anyways, so you have them once they go live here, but do not install them until that one tuesday when you see they patched china as well.
