I just moved my forum to a new host. It took us several days to get the database to the point of where I could even access it, due to the poor hosting service of the previous host.
Here is the error message (user name has been starred out:

Database error in vBulletin 4.2.0:

Invalid SQL:

SELECT *
FROM session
WHERE userid = 0
AND host = '157.55.33.34'
AND idhash = '3f0601152dfc3592e95afec8f1e250b1'
LIMIT 1;

MySQL Error : Table '********_vbulletin.session' doesn't exist
Error Number : 1146

What do I need to do to fix this?
