USPS shipping - domestic works but not international

I'm awfully confused. I've enabled the USPS shipping module and it works great. I'm several orders in but am just now discovering that it's not working for international orders. With a test account I get the "Estimate Shipping Costs" pop-up but there's nothing listed under the table header.

When I go to checkout I get this message and can't go any further:
"We are unable to find a USPS shipping quote suitable for your mailing address and the shipping methods we typically use.
If you prefer to use USPS as your shipping method, please contact us for assistance."

Is there something else I have to do to make the USPS module calculate int'l orders? Here's my info below.

Thank you in advance!

Could you go to the Tools ... Developers Tool Kit ... and do a search in the bottom input box for:
usps.php

and see what version id comes up for your files on the server?

Hi, thanks for the reply. Here's what I'm seeing (URLs edited):

Does that mean the file in 'languages' needs to be updated?

That means you need to get the current USPS January 22, 2012 file from our announcement:
