After Selecting "Visa" option, entering my address - the payment system does not proceed any further (it breaks before I can enter my credit card details) - it just response with a Non Recoverable error message.

I don't even get to enter my credit card details. See attachment. I cannot use PayPal with my bank.

Ok - im gonna bump this because I still want to upgrade my license >_>

Select debit card instead, and it should work..

Other option is directly send an email to devs..

I had fun yesterdaY.... made the same mistake....used paypal.... how long does it take for the game to recognize the purchase?

..

OK thanks - will try it again at end of month when I get paid.
