First time I tried to sign onto DDO since Update 5, I got an error "You do not have the current version of the client installed".
I went to www.ddo.com, downloaded the entire client package again, and re-installed it. I no longer get an error message -- instead, connection just hangs up. I see the words "Connecting to Cannith"... and "connecting", and "connecting". I did not see a timeout message, but probably only because I got tired of waiting and closed the program. Same on Thelanis.
