astbill admin problem

Just got Astbill up and cannot change the password. Infact, anytime I click a link I have to log back in. When I change the admin password or attempt to, I get:

Access denied
You are not authorized to access this page

And have to log back in which then refreshes the password field. So I can't change anything. I am having a feeling that this is a problem with my mysql database as I had problems getting that working but now at least can get into it.
