Thanks for your reply BlindSide,

Andrew, I'm afraid you likely have an EBSAK error here.

The HEADER_TAX_ID_NUMBER define is configured through the database, so it sounds like you did not properly run the SQL script.
How do I fix it, it have run all the SQL inserts seperately via phpadmin and it told me if their was any errors or dupicate entries, which I have removed.

Everything else seems OK

P.S What does EBSAK stand for ?
