The trouble is, these error codes are simply placeholder codes that don't actually explain the underlying cause of the problem. This is why problems with billing are so difficult to fix.

However, you said you're using 'Ultimatepay'. From what I understand, SE no longer accepts that as a payment method, as stated here: http://forum.square-enix.com/ffxiv/t...81#post2230081 Unfortunately, all you can do is try another payment method like a prepaid time card or a credit card/debit card.
