Our enhanced upgraded billing system no longer accepts international credit cards; only valid U.S. credit cards can be used for payment. If the system detects a non-U.S.-based credit card during a transaction attempt, an “invalid credit card” message will display on your screen. If you successfully subscribed with an international card prior to our system upgrade, you will need to update your All Access profile with a U.S. credit card, otherwise the auto-renewal attempt will fail at the end of your billing period. We apologize for any inconvenience.
