Kept getting the i2501 error whenever I try to pay for subscription and purchase items from Mog Station. I can redeem the 2 codes I purchased from Steam for the full game just fine, as well as a recruit a friend code.

However, anything after that wouldn't work. It never got into the part where it ask me to enter payment detail, it just display the error message directly. I tried Master Card and Steam wallet, same result. I also tried to purchase Crysta with a Master Card, same result. Using PayPal, it will just give me a "Thank you for purchasing screen" without even redirecting me to PayPal.

I am not connected through VPN or Proxy, and I tried on my Phone's 4G network as well as the network from work. Same issue.

I wanted to contact support via phone or direct chat, but my time zone is a full 15 hours ahead. That means your business hour is my midnight. EMail supports just gave me copy and paste answers that I've read and tried already. So I am running out of ways to ask for help... I just want to be able to pay for subscription, so that I know with all the time I spent in the game, I will still be able to play it after my month is up.

Any help is greatly appreciated.
