SirWorker has since been able to log in and play successfully. Based on my discussion with him - what he describes was logging in, being able to walk around but not send chat messages and then getting disconnected.
This may have something to do with the server switching bug. If you cannot send chat messages, you may be out of sync with the network and simply need to relog.
The server switching issue should now be resolved. If you continue experiencing the issues you described please let us know.
