"Sorry, we weren't able to authorize your card. Please choose another way to pay."
That's what it says when I've been trying to buy something off Gumroad. This is the first time I've encountered this problem, and to my knowledge there isn't anything wrong with my card or my account at all? I've waited a day to see if it changed, but it hasn't. I've used this card ever since I started using Paypal, and has been the only card I've linked on here. I didn't remove and re-add the card, nor did I tamper with it at all. I've even made payments before this with no problem recently before this happened. I have no idea if this is an exception or if it applies to everything else from now on. Can someone help?
