Did your sub just expire today? Or is this an ongoing problem? If this is a EU account, you can use game time cards, and that is probably the only sane solution left to you as far as I can see.

It sounds like people in certain countries are locked out of crysta and that is what the 11000 error often is. Further it sounds like the payment system does a multiple time out lock based on how far away your IP address is from the registered country.

Either way this is really terrible. I am sorry.
