Hello, I think I have a problem. I'm trying to buy the DLCs , but it says my card has got a problem (this card is also used in Amazon Store) . I don't know what that is. What can I do?
I'm afraid only Itch.io support can help you when it comes to payment processing. We don't have control over their site, only the specific game files we upload to their site. I hope things work out for you!
