False, using a VPN does not work.
At least, it didn't for me.

“Solved!”, kind of ~ Crysta does work, you must pay it via paypal.

1) Go to: https://www.paypal.com & make an account if you don’t have any yet.
2) Log into Mog Station @ https://secure.square-enix.com/account
3) Go to Square Enix Account Settings > Add Crysta
4) Select the amount of Crysta you need (1,099Crysta if you only use 1 character per server)
5) Select “UltimaPay” as payment method.
6) Select the extra choices tab & pick up “Paypal”.
7) Fill in with your account details & voilà!

It took me a couple of hours to get my Crysta, so you might have to wait awhile too, don’t stress out I had no errors or whatsoever ~ hopefully it will work out for you aswell.
