Err Code 12. What does it mean?

I am trying to use my VISA debit card to purchase hosting. It doesn’t let me do it. I purchase using the same card on all websites. I have problems only with Dream Host. What shall I do?

For what it’s worth, documentation online seems to suggest that Visa error code 12 means “Authorization Code is required but is not present”. Not sure if that’s accurate, though, or if it helps any.
