I cannot open borrowed books on my devices (Kobo Touch and Kobo Glo).

I can't open borrowed books on my ereader.  They download just fine to ADE and I can move them to the ereader however when I go to read them I get this message Oops!  This document couldn't be opened.

Have you authorize reader and digital Edition with the same Adobe ID?

[gibsmar]

Yes.  I checked on both devices

[Nanaky]

Work it with sample file: Sample eBook Library | Adobe Digital Editions

I got fed up trying to load the books using ADE 4.5 so I went back to version 3.0 and I am now able to read my books.

Where the heck can you find version 3.0?  I've been driven insane by 4.5 inadequacy in loading my Kobo Libra with books I can read!

Here you go! This is for a Mac and it worked for me TODAY for an old desktop Mac running High Sierra 10.13.6 and an old Kobo GLO HD:

Someone posted the following links in another thread on this subject; now I'm posting them wherever it seems helpful because communicating directly with Adobe for the info is USELESS (I was told by their customer service, flat-out, that there's zero support available for discontinued software and services).
