I am running version 1.9 and have had a problem with customer from Korea (South), getting an error message when the try the quote box or check out. Has any other have this problem? I am using USPS for international Shipments and UPS for domestic. I remember there was a problem with the UK and FedEx on version 1.8. I am in the process of upgrading to 2.2 and wonder if this issue has been solved with that update?
