You need to go to the Amazon web site. Select "Account & Lists," "Your Account," then "Payment Options" to update your credit card information.

If the device is purchased with a diff account you need to follow deregister process first. There can be an issue with the network too as device will no register without active internet connection. here are the steps to register kindle device.

• From Home, go to Menu, and then select Settings. Then select option My Account (newer generation devices) or Registration (earlier generation devices)
• Now you get 2 options if you have an existing account or need new account. Select the appropriate option and follow simple onscreen instructionss or contact kindle support
• To deregister the Old Kindle:
  
• From Home, go to Menu, and then select Settings. Then select option My Account (newer generation devices) or Registration (earlier generation devices).

Log in to your Amazon.com account and under "Your Account" click on "Manage Your Content and Devices." The right-hand column at the top is labeled "Settings"--click on that, and then under Kindle Payment Settings you'll see your current card listed, such as "MasterCard ending in *1234" Click next to it, on Edit Payment Method, and enter your new card's details.

Broadly this involves

- charging the battery
- connecting via wi-fi or USB
- registering it
- setting a payment method
- going shopping
