I'm having the same problem. It looks like it's been going on since the server problems from a week or so ago.
I've been in touch with games admins but they haven't been able to clear it up. I think I've shot the bug as a hung session in the TCPIP stack. Since they can't seem to indentify the hung sessions, I thinkwe'll have towait until the servers are re-booted to clear up the hung sessions.
This is a fairly common TCPIP issue.
