There have been some changes in the chat room over the last little while. Some of the old login and usernames don't work with the current version. Try sending Nathan aka cyberchild a PM (private message) regarding this. I think you can find instructions on how to do this on the main chat login page. He should be able to help you out.
Lots of love,
