Freepbx Online support not working with IRC

hi, all,

I have installed freepbx 2.2.0rc1 and asterisk 1.2.14.

everything else is fine now, except the IRC for online suport does not work.

Upon click the ‘start irc’ it prompts me to key in a nick for use, after i key in, nothing happens…

and the page just shows:
Online support

If you wish to change this to your normal nickname, you can type ‘/nick yournickname’, and your nick will change. This is an ENGLISH ONLY support channel. Sorry.

then nothing else.

any one can help me??
thanks in advance.
