Payment Method Registration Errors [Error Code 401 and 601]

[XioNightshard]

Getting Error 601. Don't feel like buying Crysta or buying a time card that may or may not work. I did get a new debit card between payments but it won't let me update the card information due to this error; the bank isn't the problem as I've already checked and given clearance back during the first payment.

If you can't be arsed to fix the system, I guess I'll take my money elsewhere. :/

Edit: Working now. Out of curiosity, I tried this again, but globally disabled NoScript and Adblock just for the attempt. It went through without a hitch; don't know if anything changed overnight on SE's end but if this was actually my fault I figure I should mention it in case it helps others.
It doesn't work to only whitelist mog station/SE, by the way, as the payment processing service connects to a different site with its own scripts (this was mentioned earlier in the thread as well).
