flexi auth - A user authentication library for CodeIgniter

[eluser]code_has_been_ignited[/eluser]
I have jut installed the library and have coded a registration form. Nothing special but its allowing me to become familiar. The reg form currently does not vary by much from the demo included with the download.

When I submit my form to register a user I get this error message:

Code:

You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'WHERE () IS NULL' at line 2

SELECT COUNT(*) AS `numrows` WHERE () IS NULL

Line Number: 330

Any ideas on this? I installed everything par the instructions and the demo installed in a separate folder seems to work fine.

Thanks for any help
