My name is***** am sorry to hear that you are having this issue.
I will be glad to assist you with this.
Try this please> this may be caused by a glitch in the firmware and can be resolved by a forced reboot, then your kindle will work normally again. Slide or press and hold the power switch for 40 seconds, then release. Then check for the downloads. If this fails let me know and we can try another option.
did that work for you?
