I have a CE 1.0 version of FFXIV. My trial period just ended and I was updating billing info. However, I keep receiving the Error 601 and sometimes Error 401 from the SE msg.

I have had no problems paying for this account back in 1.0
I also use the same credit card information with my FFXI accounts and have no problems paying.

Lastly, I double checked with my bank and they have no blocks on the cards I'm trying to use to pay for the subscription.
