Get someone at card services at your bank and see what response code they see when Adobe tries to process the payment.
There's no payment to process. I'm trying to enter current and valid payment information but Adobe's system incorrectly rejects the data.
I see you have s subscription under the same Adobe id as with forums. The card details have now been updated.
please let us know if there anything else we can help you with.
I'm experiencing the same issue, did yours get fixed?
