(10401) order error with one language, other two works fine

[Nandor]

Hi All!

Some days ago you helped me to solve order email, paypal express payment problem. It worked fine.
I was making trial orders to see if everything is fine and it was with two languages, but the third one.
The site has: english,german,hungarian language. The buying with english and german language works fine, but with the third,hungarian, language the costumer gets this message, attached a screenshot.


it says, if you cant read it, :

an error occured when we tried to contact the payment processor.please try again, select an alternate payment method, or contact the store owner for
assistance. (10401) 10401 Transaction refused because of an invalid argument.
See additional error messages for details-- Order total is invalid


plus i (admin) get this to email address:
10401 Transaction refused because of an invalid argument. See additional error messages for details. - Order total is invalid.
