Issue with a kindle ebook? --

Hello, I am trying to change format of my kindle ebook but I am not succeeding. I've downloaded the Kindle app onto my pc and one of it's folders where the e-book is contain 6 files. The 2 files which I thought I could use to do the converstion ends with .azw and the other with azw.md. But when I try to convert the file . azw I keep getting an error message. Whilst the other doesn't work at all. Can you help me please? I would like to convert it to a epub format. Thank you.

The YouTube home page displays as blank white and only with grey box outlines where full video preview frames should be visible ? There appears to be a thin banner of what the page should look like at the top of view frame, but over 95% of the frame is blank white, with grey box shapes on the left side of the screen.
