Hello Patricia ,
Please avoid sending a same query in different mediums. You may get duplicate response(s).
“The payment gateway throwing an exception, when you are trying to purchase the AxCrypt Business subscription.
The exception/error message is “Your card is not supported for this currency. Please use a Visa or MasterCard card.”
That means the card does not accept the selected currency. So please try to purchase the business subscription with some other different cards or other currencies which was supported/accepted by the card provider/issuer.
