Payment Method Registration Errors [Error Code 401 and 601]

[morpheurenequi]

Are you registering through MogStation or the account management page? If the former, try the latter - that's how I registered mine. In the Lodestone: Help&Support > Square Enix Account Information > Square Enix Account Management System > Register/Update Payment Method. If you succeed, then go to MogStation and try setting up your sub.

If that doesn't work either, I have no idea. ): Good luck.

Well, thanks for the good luck wishes. It shows me the same Error 601... =/ I'll never understand a game that don't want money and more subscribers...
