I tried to use UltimatePay to do just what you did, using PayPal and failed totally. UP never helped, PayPal confirmed that the payment request had been made then immediately voided by UP: I never lost any money but didn't get Crysta either.

It also failed to work using a Credit Card.

I don't know about the game card you're using, but may be worth checking if, like my PayPal account, it never got 'charged'.

SE's account system is crap, many people suffer error 401 or 602 (or something like that) which is caused by SE account details (name and address) allegedly not matching the details provided by the payment processor when patently they do.

The only way I was able to buy Crysta was with Paysafecard's 'token' system which means you simply enter a 16-digit number, since there are no personal details to compare SE's account system is happy and I got Crysta.

I used UP+PayPal for several years when FFXIV V1 launched, God know when it broke but it's been broke for sometime and neither SE nor UP seem to care a damn.
