Chat Installation on Word Press 3.2.1

OK, so when I searched plugins I saw that chat was supported all the way back to WP 3.0.0

I successfully installed and activated chat, However, when I went in to manage chat via chat settings panel, the screen is totally blank.

Do I need to edit something in one of the files to get this to work? Or can you send me an older version of the plugin that will work with a Wordpress 3.2.1 (Twenty Ten) Installation?
