Try this:

1. Double check the credit card number and expiration date you entered.
2. Did you select the type of credit card? (Visa, Mastercard, Americal Express, Discover)
3. Usually it is only a temporary problem with the service that verifies your credit card information. If everything looks okay, just keep trying and eventually your card will be processed.
4. If this does not work and you get an error message when trying to process your credit card, please contact us and let us know what the message in red at the top of the screen says. We will be happy to help you out.
