Taxation Auto-Refresh And Select By Shipping Country

Hi guys,

I made taxation depends of shipping country and I added Country as Select Option, however when Customer changes his destiny of delivery the item the taxation is not automatically reloaded. For example if I change from UK to US the tax is visible as UK. Do you have any idea how to push the form to reload or recalculate taxation?

Also on demo version, taxation is not updating automatically:

I have free shipping so the message of update rates is never available.

Anyone has experience same situation? Their support is useless: "Unfortunately, you have run out of your support credit balance, so now we cannot render you assistance free of charge".
