Problem with ADE and DRM

Try this to fix problem with Kobo "not authorized to open.." error after downloading books from Library: 

Open ADE on Mac (I have a MacBook, don't know if this works on PCs as well)

Connect Kobo to Mac.

Highlight Kobo in ADE menu.

Click on little wheel above and to the right of the Kobo to open authorization menu.

Click on "Erase authorization". Kobo is now de-authorized, but ADE on your Mac is still authorized.

Select a library book that’s available to borrow from library website, click on "Download" then click on the downloaded ACSM file. The book will then open in ADE.

Click on ADE Library to see list of downloaded books.

Highlight the book you want to transfer to your Kobo. Double click to open menu, click on "Copy book to Device".

The Kobo will get authorized automatically (remember, it's connected to the Mac, and ADE on the Mac is still authorized) as the first part of the process, and then the book will tranfer to the Kobo. The authorization-download process is very quick, and it's easy to miss seeing the message that the Kobo is being authorized first.

Eject Kobo. Book can now be opened on Kobo.

Try it-- it worked for me. Hope it works for you! 

(Thanks to the Mireille at the Ottawa Public Library for sharing this fix with me. She said you many need to repeat the process periodically.)

Same here...it's not very nice when they don't care much about helping.

Maybe it's a software issue on their end anyway...

Day 2 not being able to access any of my books on ADE.
