I have the same problem. My subscription expires in 3 days. I had plenty of crysta but decided to buy a wedding plan with it and then buy more crysta. Took the crysta but gives me both 601 and 401 errors when I try to buy more. I also got it when I tried to update my card in case that got messed up. I have never had this issue before. A friend suggested changing browsers so I did. No change.
