I can't buy X-Plane 11 Beta

Question

For some reason, i can't buy the digital download of X-Plane 11. I get stuck in the checkout page because it says "check your billing adress and try again". I live in Brazil, if that helps finding a solution.

Answer 1

All I can say is to ensure all billing information, including payment information, is completely correct and chargeable.  

--> Remember, all credit/debit card information must be correct, and must correlate to the address to which you had input.
