Payment Method Registration Errors [Error Code 401 and 601]

[Arkaya]

So, after weeks of trying different cards, changing accounts, different banks, different browsers, different methods, I finally found a 100% fool proof way to get around this problem...

Quit trying and play a different game!!!

No really... But I did figure something that worked for me anyway.

Go sign up an account for UltimatePay (I couldn't actually log in, but I had the account made)
Then I went and bought Crysta and when it asked me for payment method I always tried my debit/credit card to no avail, I received the same errors as given by the MogStation...
So instead, I used UltimatePay as a method of payment even though I had no game card or anything other than an account made
I put in my information and boom, it worked, I was able to buy crysta and use it to get in

So 2 weeks later...

Was it worth it? Probably not, this is one annoying system
