Any of you guys know how to extend the subscription? I want to add another month game time to my account. I only have paypal so I can only use the crysta (via UltimatePay -> Paypal).

I tried this :
Mog Station -> Account Services -> Subscription Services -> Select Crysta

But all I got is this kind of screen, showing 0 Crysta



So I can't extend my subscription while my subscription is still active??
