I am using Smith.BuyNow03.08.00-DNN5 in my dotnetnuke portal.

I selected "Custom Ship Methods By Weight" as shipping setup in module setting.

And I made several "custom shipping method" and "shipping by weight" in "shipping" page of "store admin menu"

when I add some products to cart and go to checkout page I have some trouble.

on the checkout page if I don't change the country I can see the list of "shipping method" and everything is ok.

But when I select another country the list of shipping method is empty.

for example, when I select "japan" as "country" I can't select "shipping method" because the items of it are disappeared.

what is wrong ? what should I do to keep "shipping method" ?
