Vbulletin error emailed *HELP*

[howard007]

All of the sudden I get these errors and I've been running vbstopforumspam for a couple months. How do I fix?


Database error in vBulletin 4.0.3:

Invalid SQL:
INSERT INTO vbstopforumspam_log (date, ipaddress, email, username, message, blocked,
userhash) VALUES (now(), '91.121.85.126' , 'larrypae@gmail.com', 'Unregistered',
'Result on field username - Unregistered [REMOTEERR] Unverfied but allowed by
policy', 0, '677850e24e7b5900768632062e50c3f7');;
