Remember that you should be trying to join Laanx server, not Localhost.
Now then... if it says Fail, and doesn\'t let you connect, it\'s likely that it\'s down for maintainance or it just crashed. You can check server status at
http://laanx.fragnetics.com (wait a few minutes and refresh the page a couple of times- the status is taken every 5 minutes or so).
Assuming it says \"Online\", try to join again. If you still can\'t, you may have a troublesome firewall or router blocking the traffic.
Do you?
