Forum Database Error when deleting Forum
 

I am trying to delete a forum and receiving a Database error.

HTML Code:
Database error in vBulletin 4.0.2:

Invalid SQL:
DELETE FROM moto_access WHERE forumid IN (18);

MySQL Error : Table 'trlforummoto.moto_access' doesn't exist
Error Number : 1146
Any suggestions of what this might be?

thanks.
