Does not handle database prefix - directly calls mysql functions

I have a database prefix on my database tables. This module does not work with this. It directly calls mysql functions when it appears it should call drupal routines to handle this sort of problem

warning: mysql_fetch_row(): supplied argument is not a valid MySQL result resource in /home/missions/www/gamma/sites/all/modules/profile_enforcer/profile_enforcer.module on line 203.

Code needs to be rewritten!
