If *Connecting to Karaoke (6667)* Unable to resolve server is exactly what you see, then your problem is that you aren't trying to connect to a valid server address. "Karaoke" isn't valid. It should be something similar to "irc.Karaoke.org" or "servername.Kakaoke.org" or whatever. "Karaoke" may not even be part of the server address.
You're going to have to figure out what the server/network is and use that to connect.
