I have purchased 3 books which are in my ebook library but I cannot transfer to Reader or open them. My PC is authorized by Digital Editions and ebook library states PC is authorized for Adobe DRM. I was able to read the books on my PC before I authorized Digital Editions. I must confess I downloaded books before authorizing Digital Editions....could this be the problem?
As I suspected...it was because I had not authorized my pc before purchasing books.
Easy to rectify...just delete the bought books in your ebook library and then return to ebookstore and download your order again. (I think most ebookstores allow you 3 attempts at downloading.)
