Fatal Error on Rebuild of db

I am getting this error when trying to rebuild my database to push members through to vbulletin:

I have done up 2 manual inserts, one into the members table and one into the payments table. Maybe I mucked something up?

Can you revert to a backup just prior to your manual inserts?

If it works then, you know that you mucked something up with the inserts.

Good advice, the data field was empty and it was messing up everything.

Fixed now.
