Problems with PM system after upgrade to 3.7.0?

I have VBSEO 3.1.0, upgraded to Vbulletin 3.7.0 last night and looks like my private message system is kaput.

Foilowed all the instructions from vbulletin, they're thinking it's got to be VBSEO since.

Anyone have any similar problems? My mtop is producing results like:

10574492 jcvb2 lma3075:51646 jcvb2 1610 Query Locked UPDATE pm SET messageread=1 WHERE userid=1433 AND pmid=204959
10574625 jcvb2 lma3075:51783 jcvb2 1566 Query Locked UPDATE pm SET messageread=1 WHERE userid=1433 AND pmid=204959
10576428 jcvb2 lma3075:53634 jcvb2 1168 Query Locked SELECT ... fromuserid AND userlist_ignore.type = 'ignore') LEFT JOIN icon AS icon ON(icon.iconid = pmtext.iconid) WHERE pm.userid = 3318 AND pm.me
10576566 jcvb2 lma3075:53774 jcvb2 1133 Query Locked UPDATE pm SET messageread=1 WHERE userid=1433 AND pmid=204959

and such. Ideas?

Did you repair your tables?
Seems that some tables might need some care. Locking shouldn't have to do with vbSEO.

Hello,

this query is not a part of vBSEO code.
