I pre-installed my card and it worked. Thanks a lot!!!

I selected the "Buy now" option, and tried to pay with Ping and my Visa Card. And each time I click on "Complete order", a message pops up, stating: "The 'Pay by other means' option is restricted to authenticated members. You can either purchase this item using a credit card, or become authenticated by crediting your account with $10. " I don't understand this message as I'm trying to pay through Ping with my credit card, not "by other means"...
