No, I don't think that my country has something to do with this. He pays to FastSpring, which is a payment processor similar to PayPal. In FastSpring I see different errors that happen let's say once per week. In this case the error was something that the address of the card is wrong, or something like that. If you ask me, I don't care about anyone's address, name, or whatever. But I guess that FastSpring has some rules and they are making some checks before payments... I don't know.
