found this on the Administrators board:
07:38 PM EDT Re: error for chat room
All you need to do is disable your firewall before loging into the the site. Once you enter the chat room, you can re-enable the firewall. To disable the firewall, fine the icon in your system tray that looks like the globe. Right click on this and at the top it should say something like Norton Personal Firewall. At the bottom of the listing, it should say disable. Just click on this and it will turn off while you are logging into the site. Join the chat, and the right click on that icon again and click on enable. You are now in the chat room and your firewall is back in service.
Hope this helps.
PS This is how I used to get into chat when I was active in there.
I tried it last night and it worked like a charm.
