I'm not tech savvy, just the basics.
I have ADE on my apple tablet with all my ebooks.
I want to get ADE on my windows desktop.
I have downloaded ADE windows on my desktop and logged in to my ADE account.
I can't see my ebooks on my desktop?
Can you assist me please?
How do I see my ADE ebooks on my ADE windows desktop?
