You should be able to just comment out the "defaultPC=mike 0" line in client.conf. I'd put things back to Player. Player denotes the service name to connect to on the host/port specified before that. I really need to write the documentation for the config files.
I'm logged in currently (though may be afk for a bit). One thing I noticed last weekend is that chat is broken, so if you do catch me online, it may not be too easy to communicate. You can bring up the currently useless chat window by hitting F2. By the way, the
ClientUserInterface wiki page is pretty good for explaining which keys do what.
