flexi auth - A user authentication library for CodeIgniter

[eluser]Unknown[/eluser]
I'm hoping that someone can help me. I'm new to CodeIgniter and to Flexi Auth. I've got everything up and running using the demo files as a guide. Problem is, after I've logged in, if I hit refresh or go to a link, it kicks me back to the login. If I hit the refresh button, I get this DB error. Can someone explain to me what's going on and how to fix this issue?

Error Number: 1054

Unknown column 'user_login_sessions.usess_uacc_fk' in 'where clause'

Nevermind, I figured it out. Some how the session preferences in the config file for timeouts got changed.
