Thanks to you too. I thought of something after I started the thread

I have a decrepit (as in falling apart) laptop which has ADE on which I don't use. Thought it best to deauthorise ADE because of device limits. I did that and uninstalled the app. I then downloaded a random book to that laptop. Of course, it wouldn't open but I emailed it to myself and was able to open it on both my phone and my new laptop.

So thanks again to both of you but I seem to have confirmed your thought and answered my own question!

But perhaps it will help others who have had problems opening ADE which is pretty common I believe.
