TICKETMASTER HELP

Hi guys, in preparation for Trish's show tickets tomorrow, I added my credit card to my Ticketmaster, however, when I hit edit payment method to doublecheck if everything is right, I am getting this:

"Due to the selected country on the billing address you are unable to continue with the purchase with this card.
You can continue to save this card to your account but please choose a different payment method before placing your order."

Nothing is wrong with the billing address or card numbers, and the country on my card is United States, as if my account. Anyone else have this issue? I'm nervous I won't be able to get tickets tomorrow because of it and can't find anything online about people having similar issues.
