Metodo di pagamento

Hello, sorry if I write to you here but I have not found a support email on the site. I am willing to purchase a license of your software but as a payment method I only find Visa to Mastercard credit cards. I have the possibility to use American and Paypall. Is it not possible to use either of these two systems? Thanks for your availability.
Yours sincerely

Hello Scuffi, I am afraid that we do not support PayPal or other systems for now.
Could you show me a screenshot of the problem? Why the credit card failed to make the payment?
We are trying to solve this kind of problem, so it would be good if you could share more details. Thanks in advance!
