Hi,
Can someone explain to me what I need to do to solve this problem:

Database error in vBulletin 3.6.1:

Invalid SQL:
SELECT * FROM forum WHERE forumid='42';

MySQL Error : Table 'extre9_vbulletin.forum' doesn't exist
Error Number : 1146
Date : Wednesday, November 8th 2006 @ 04:28:05 PM
Script : -----------------------------------
Referrer : ----------------------------------

Classname : vb_database

I have alot of problems recently when I tried to install VbAdvanced on my forum. First the template looked screwed up then after un-installing vbadvanced followed by the template things got worse the more I tried to fix it. Everything on my forum now seems to work apart from this one error. Can anyone on here tell me what it means and show me how to fix it, please?
