Error 1054 in admin panel

[putergirl]

Hello, a while back I tried to update my forum from 3.7.0 to something more updated and it didn't go well. I had errors all over the board and after days of trying to fix things by hand I reverted to an earlier date. Since then I have this error when I log into the admin cp and I don't know how to fix it. Thanks in advance from someone who doesn't know how to program.

Database error in vBulletin 3.7.0 Beta 4:

Invalid SQL:

SELECT COUNT(*) AS count
FROM moderation AS moderation
INNER JOIN post AS post USING (postid)
WHERE moderation.type='reply';

MySQL Error : Unknown column 'postid' in 'from clause'
Error Number : 1054
