We attempted to charge you this month, but your card was declined and your subscription has been put ON HOLD. In order to continue your account, you must cancel your current account using the CANCEL SUBSCRIPTION button and then purchase a new subscription

So, I have to cancel my subscription? I don't lose my characters if I do that, do I?

No, it's just as if you were switching payments from one credit card to another.
