Hi there. My name is*****'m sorry that you're having this problem. It would be my pleasure to help you resolve it. Before troubleshooting the Kindle, please click on the following link and login to your Amazon account. Scroll down to Amazon Wallet > Payment Methods and click on Manage Payment Options to be sure that your new payment information has been saved to your account. If it has not, please add it and save it and then sync the Kindle. If it is already there, please continue with these instructions:
This problem and many others are often the result of a "glitch" in the software. Luckily, it is easily fixed by resetting the Kindle to Factory Settings and setting it up again. Please don't be concerned about losing your books. The books that you have purchased from your Kindle will continue to be available at the Amazon website under My CONTENT if you should wish to download them again at some point in the future.
Please do the following:
Remove the charger from the Kindle and hold the power button or switch in the OFF position for a full 40 seconds. This should reset the Kindle to factory defaults. You will know that it successfully reset to factory defaults, if it reset the Kindle back to the way it was when you took it out of the box. Did it do that? If not, please try it again, being sure to hold the power button for a FULL 40 seconds. If it did require you to set it up again, then the factory reset was successful.
If this did not work for you, please tell me exact model of your Kindle. If you're not sure, please look for a serial number. If you can't find it on the Kindle itself, you can find it on the Manage Your Kindle page of your Amazon account (in the Manage Your Devices section).
Downloading Books To Kindle After Factory Reset
After resetting the Kindle, just make sure when you set it back up that you use the same Amazon email address and password ***** you are currently using. After setting up the Kindle, please login to your account at Amazon.com. Select YOUR ACCOUNT. From the drop down menu that appears, please select MANAGE YOUR DEVICES AND CONTENT. On the page that appears next, you will see a CONTENT Tab and a DEVICES Tab. On the CONTENT tab you will see all of your Kindle book purchases. You can sort them by title, author or purchase date. Please locate the book that you want to download to your Kindle, select it by checking it and then click on the ACTIONS column. Choose deliver as the action. Select your device from the Device list. If you have more than one Kindle, make sure that you choose the Kindle that you are actively using. Don't select the Kindle Cloud reader unless you have downloaded the Kindle Cloud Reader APP to a computer or device other than your Kindle and wish to read it there.
