GT-chat Issues!

[egidesign]

I have wanted to install a chat on my site, a good one, and I used the app vualt. I saw GT-chat, and thought, "Man, this is great software!" well, I filled out all of the information to install it, and whenever I want to my site /chatter, it takes me to my 404, then it says in the adress bar: http://www.egidesign.net/cgi-bin/@@INSTALL_PREFIX@@/chat.pl I really have no idea how to fix this, I searched and looked on their site and everything.
