Please reset the kindle by holding down the on/off switch for 40 seconds (use a watch to time) ignore any messages the kindle may display, then release your finger the kindle should reboot and re-load the operating system, you may have to do this both on and off the charger and upto 4 times before it resets.
We find software corruption can cause issues like this resetting clears this
Let me know if you need more help
