Sorry for any trouble, @FSB.
Check out this thread if you are receiving that error message when you attempt to update your credit card: Error Message: "Sorry, your payment information is not valid"
In the meantime, I have also created a ticket with our support team for you.
They will be contacting you privately via email to help look into this further, so please keep an eye out for their message.
Thanks for your patience in the meantime!
