Trying to do a credit note but...

I am currently trying to put an item back into stock doing a credit note.  The item was invoiced back in 2006.  When I try to post the credit note I get the following error:

Invalid Input.  Tax Class 0 is not in the range of 1 through 10.

I have checked our tax classes for that customer, and for that particular order/invoice.  It is set to 1.  I have checked the GST class, the fields are set up properly.  Any reason why it would be doing this?  If so, how do I change it so I can post the credit note?

Any help would be greatly appreciated.  Thanks so much.
