Suite timeout on upgrade_400a1.php?step=3

[محروم.كوم]

Can anyone shed any light on this please? It keeps hanging on step 3 of an upgrade. It also says the error is in vb 3.8.3 - that's fine... but the database snapshot was taken from vb3.8.4PL1 - not 3.8.3

PHP Code:
Database error in vBulletin 3.8.3:

Invalid SQL:
INSERT INTO vbtagcontent
(tagid, contenttypeid, contentid, userid, dateline)
SELECT tagid, 2, threadid, userid, dateline
FROM vbtagthread
ON DUPLICATE KEY UPDATE contenttypeid = 2;
