Force Hack Removal

[LCN2007]

I am trying to remove an obsolete mod on my site but a while back i deleted the SQL Database that was attached to the hack so now when i try to remove it i get the following error:

Database error in vBulletin 3.7.2:

Invalid SQL:
SELECT COUNT(*) AS users
FROM user AS user, userfield AS userfield

WHERE userfield.field55>0
AND user.userid = userfield.userid;

MySQL Error : Unknown column 'userfield.field55' in 'where clause'
Error Number : 1054

I thought a while ago i saw such a hack to force remove mods when such things happen.

any help is appreciated,

Thanks
