Draft Control for WP 2.0?

I wish to use the Draft control plugin on WordPress 2.0 but I get errors when using the current version.
http://wp-plugins.net/plugin/draftcontrol/
Hope someone can help, the error I get is:

WordPress database error: [Unknown column ‘user_firstname’ in ‘field list’]
SELECT ID, user_login, user_firstname, user_lastname FROM wp_users WHERE user_level <= 10 AND user_level > 0

And the time column just shows 0000-00-00 00:00:00 regardless of when it was posted.

Thanks
