SQL problem

I installed this module and get this error message at admin/user/user/suspend. I haven't suspended any users BTW.

user warning: Column 'uid' in group statement is ambiguous query: SELECT COUNT(*) FROM user_suspend_users u LEFT JOIN user_suspend r USING (uid) LEFT JOIN user_suspend_users_roles ur USING (uid) LEFT JOIN user_suspend_node n USING (uid) LEFT JOIN user_suspend_comments c USING (uid) WHERE u.uid != 0 GROUP BY uid in /home/ca/public_html/includes/database.mysql.inc on line 172.
