IRC help (swiftswitch)

[Jrbaker]

I'm currently trying to use the built in IRC in the swiftswitch program, ever time I click enter chat it says

* IdentD listening on port 113
-
(14:38:21) * Connecting to server irc.swiftirc.net:6667 (6668)...
-
(14:38:21) * Unable to resolve server
-
(14:38:21) * Disconnected

Anyone know how to fix this??
Please help it's really needed.
