If you can open the eBooks on Digital Edition the Adobe ID und the eBooks are fine.
Have you authoirze the Reader with the same Adobe ID?
Yes I did. In Digital Editions I clicked on the eReader device, then in the options, clicked on Authorize Device. The email address and checksum / unique code is the same.
Both things are authorized. There is nothing that I can see that's wrong.
Even re-downloaded the books again from the library after authorizing, and the issue is still happening.
Does the public library save any information on my account? I'm think that because it did not the first time, it won't work for the duration of the book rental term.\
I've retried all the steps from the very beginning,, as it was the day I bought it (factory reset so the device is like new, re-installed the Kobo Desktop, re-installed Digital Editions, authorized the computer and eReader, and downloaded some books). It still happened.
I may have to wait until the books are returned to the library to try this again.
Normal was linked the eBook with you Adobe ID for the 14 days.
Get you the same error when you try to open the eBook in Digital Edition?
I can read the book in Digital Editions on my computer. Its only on the eReader itself that I receive that Digital Rights message. On the computer in Digital Editions, it is fine and works.
Only on the eReader device that this is happening.
In this case try reset the Reader (before save ebooks) and authorize again with your Adobe ID. Then move again the eBook to reader and try to open.
