This... I have this exact same issue... I can't pay for FFXIV now (buy subscription) at all... I had to lend my friends paypal with his card attached to it to be able to pay for 30 days of sub -_- Square Enix please... do not do this to me.

ALSO I contacted PayPal some companies NOW REQUIRE a credit or debit card added to theirs account, apparently Square Enix must be one of them, as soon as you get account with added credit card to it you can pay normally from your paypal wallet.

Square Enix please make something that we can pay with PayPal without having our Credit or Debit Card added to our account, especially those of us that doesn't have any card at all, like me.
