I was playing the game earlier today, logged off, and when I attempted to log back onto a character, a message popped up saying that my character had been booted from the world. I clicked the "ok" button and it closed the client.
I logged back in and discovered that I no longer had my VIP subscription and the store would no longer accept my CC to renew it.
It returned the following error code - "1058: The payment was declined. Please contact your bank for more information."
I have absolutely no idea why my recurring subscription was cancelled.
