ok so I tried to buy your game with a new card and i get an error like this : Your payment was declined by your bank. Please try again later or contact your bank for more information.
I called the bank and they told me the card is active ... its working perfectly and the required ammount of money is on the card... so they believe it's 100% a problem with the site or the product .... not the card.
What do you think Indi ? Should I send you an email with all the details ?
