If it is the latter, not sure but maybe your ISP is blocking the protocol.
That probably sounds like technological mumbo-jumbo, but the bottom line is if you can't connect through the applet in the browser, you need to get a client program and connect through that. There's a few guides on the web for connecting to IRC, depending on the program you use. I recommend using XChat 2, which has a free Windows port and a pretty good setup guide.
Question -- does the channel not work with Chatzilla? I have Chatzilla installed but I'm not sure if that could be of use.
