Good morning and thank you for posting on the Final Fantasy XIV Technical Support Forums.

I'm glad you were able to find a resolution to your 601 error. I'd like to clear up some confusion on this issue. A 601 error is a billing error, not a technical one. The system does not ban your card when this happens, however, multiple failed attempts can make the error worse. Additionally, you can pay for anything on the Mogstation with Crysta if you run into this error, including retainers.

I'd suggest contacting the Square Enix Support Center if you receive this issue in the future. As this issue has been resolved, this thread will be moved to the 'Separate Support Required’ subforum.

Thank you for visiting the Final Fantasy XIV Technical Support Forums.
