Hi,
In order to work properly, the UPS & USPS shipping plugin require a valid address in the US.
Afterwards, if there is no shipping method HikaShop display an error message in the checkout.
Please be sure that your template is compatible with the Joomla messaging system so you can see messages.

By the way, do not send me private message, use the "contact us" form instead.
