ImpEx not loading.....

[hostmela]

Hi please assist me.

I get this error when trying to open Impex in my ACP. It offers to take my customer number, says success then freezes; now it displayed:

ImpEx Database errormysql error: Invalid SQL: INSERT INTO vbfields VALUES ('childlist', 'forum', 'N', '!##NULL##!', 'return true;', 'vbulletin')

mysql error: Table '*********.vbfields' doesn't exist

mysql error number: 1146

Date: Sunday 18th 2009f October 2009 08:41:20 PM
Database: *******
MySQL error: Table '****.vbfields' doesn't exist

I have looked and the database does indeed exist
Also sometimes I get an internal server error....
