Chat not working for users with specific user role.

I'm using the chat plugin on a wp site I'm working on. For login options I chose wordpress user. It works fine for admins and some other user roles but there is one user role that can't use the chat. I was using the chat lite before and it said you must be logged in to use chat (even though I was) and now with the paid version it just doesn't show the chat box at all if logged in a this specific user role.
