Payment Method Registration Errors [Error Code 401 and 601]

[Lament]

It was the process I went through first and seemed to work for me, hence why I'm not sure if it would work for anyone else. It could just be I got lucky, or that something about my CC helped.

Before, I was trying all the wacky workarounds for Crysta that SE support told me to try (because I was wary about trying CC after reading about all the failures here). Since I was running out of free time I decided to bite the bullet and try the CC method after all, and since I saw a lot of the issues here specifically mentioned going through Mog Station, I decided to try registering my card via SE Management instead.

I honestly don't know if it'll work for anyone who got 401 and 601 before. But if anyone here hasn't tried yet, I'd recommend going by my method just in case it wasn't a coincidence. And if it was... I suppose continuing to try could help? If I got lucky, it at least means getting lucky is possible.
