Hello, and thank you for using this service.I will help you now.
Do you have an actual Kindle device, or are you trying to read books on your Macbook pro?
A remote connection would be the fastest and easiest way to fix/diagnose this problem for you. I sent you an offer for remote services so i can connect and fix for you while you watch and communicate with me. There is a satisfaction guarantee, and it also includes phone support. Would you like remote services?
