Figured it was time to come back after the initial crowd had settled. Now I'm getting error 401 too when trying to register for automatic renewal. This is a rather ancient problem from when the game was released, so its disappointing to see that it is still not fixed. You would think that a bug free payment system would be rather high on the priority list. I'm reading that time cards don't seem to be working consistently,so I'm not buying one.

Trying again tomorrow, then its "See you sometime next month XIV!" or well D3 DLC ..

Good luck to anyone else who is facing the same problem!
