Action issue (Need help asap)

[corn dog]

My website was recently hacked a few day's ago. I have imported the back-up and I cannot open the site yet because I get this error everytime I want to:

Delete a thread
Make a thread
edit a thread (or post)
And anyaction that has to do with threads...
I get this error:

Database error in vBulletin 3.6.0 Release Candidate 3:
Invalid SQL:
DELETE FROM toonstin_forumpostindex WHERE wordid IN (0,905,13,4511,832,3701,38,3440,363,2976,177,107,1091,2993,99,56,22,1376,304) AND postid = 6085;
