My situation seems a bit different than what others are posting. I never get to enter any payment info at all. As an existing customer, I may have an expired card on file. This is likely, but I can not confirm. The payment info flashes momentarily, too fast for me to even read, and then an endless "processing" loop.
As the mod suggested, I have emailed. We'll see what happens but it seems clear affinity have a problem affecting many existing and prospective new customers. Not even sure I want to try with my cc now as many seem stuck with payments being held back but getting no license. I don't want to join those unfortunates.
PS: Received only an automated reply to my email, informing me there will be an extended delay in any reply. Affinity has a major mess on their hands.
