When I attempt to purchase CAP, the following error pops up: "Is unregistered card to the authentication service. Or re-enter at your registered card, please contact us to have your credit card company." I am using a VISA, and it has worked with this in the past, but for the past few months, this same error has popped up. I have tried several cards (all VISA) yet the same error pops up. Any suggestions?
