Creating an Invoice line item generates error

I just downloaded the current official release for drupal 6.x and I am quite excited to begin using this module. It is looking good so (other than CSS issues in my theme) far but when I went to create an invoice line item I received the following:

user warning: Unknown column 'vatpercent' in 'field list' query: INSERT INTO storminvoiceitem (vid, nid, invoice_nid, amount, vatpercent, vat, total, weight) VALUES (8, 8, 6, 3400, 0, 0, 3400, -10) in /home/content/b/h/o/bholmes451/html/bghdrupal/modules/storm/storminvoiceitem/storminvoiceitem.module on line 262.
user warning: Unknown column 'vat' in 'field list' query: SELECT SUM(amount) tamount, SUM(vat) tvat, SUM(total) ttotal FROM storminvoiceitem WHERE invoice_nid=6 in /home/content/b/h/o/bholmes451/html/bghdrupal/modules/storm/storminvoiceitem/storminvoiceitem.module on line 291.

I believe this is related to the most current release changes for the VAT to TAX.

Thanks,
