sambamu, we have updated Ecwid code and add some additional features, that allow to use Google Checkout for international orders. This change will appear in the next Ecwid version(1.31). The current Ecwid version is 1.30.
You can always check the current version by looking to the right side of the footer in Ecwid Control Panel. Also as soon as our servers are updated with the 1.31 version, I will post a message here.
And thank you for your report!
