Just to throw in my 2 cents -
AT&T Uverse in St. Louis, MO. I have done the router re-start and dns flush. I filed a ticket last night, but haven't updated it.
My husband's is stuck at Initializing.
I have two copies installed on my machine, and the first is also stuck at Initializing. The second gets past that, then is stuck on "The underlying connection was closed: Unable to connect to the remote server." THEN, for giggles, I tried Lamannia, and logged right in with no problems, but got the red connection-icon-of-doom and was booted.
Y'all have made me pull out my old Diablo II CD again. Ahhh, nostalgia!
