My name is***** am sorry to hear that you are having this issue.
I will be glad to assist you with this.
This is usually caused by a glitch in the firmware and can be resolved by a forced reboot, then your ereader will work normally again. Slide or press and hold the power switch for 40 seconds, then release. Please let me know the results.
