After hearing the suggestions from other users about buying Crysta through Ultimate Pay with an Ultimate Gamer Card I decided to give it a try. I agree that this is not a fix for anything. It's ridiculous that I couldn't use my card to buy a subscription through SquareEnix but I was able to use that same card to purchase an Ultimate Gamer Card through WalMart to then purchase Crysta with through SquareEnix. lol

I went to Walmart.com and purchased the Electronic Delivery $20 Ultimate Gamer Card. I received the PIN number for the card about 30 minutes after I made the purchase.

I went to the Mogstation and purchased 2000 Crysta using the Ultimate Gamer Card and everything went through smoothly.

However, as other users have mentioned I will now have existing Crysta that I may not be able to use unless I purchase another card next month. Honestly, If there isn't a fix by then, I may have to do that anyway.
