The solution to this problem: Deauthorize your Kobo and then deauthorize your computer (ctl-shift-D). Uninstall ADE and reboot your computer.
Install ADE V 2.0 and reauthorize computer and Kobo.
Avoid upgrades to ADE!!! ADE 4.0 and Windows 10 and Kobo do not play nice.
If the above does not work (it did not work for me):
Delete the "My Digital Editions" folder from Downloads
Deauthorize your Kobo
Deauthorize your computer (Ctl-Shift-D)
Uninstall ADE 4.0
Reboot computer
Install V2.0
Reauthorize Computer and Kobo
You need to delete the "My Digital Editions" folder in Documents
Deauthorize your device
Deauthorize your computer (Ctl-Shift-D)
Uninstall ADE v4.xx
Reboot
Install ADE V2.0
Reauthorize computer and Kobo
Forgot to mention - before installing the old version of ADE - delete the folder "My Digital Editions" in Documents folder
June 2019: I haven't been able to download or open library books for some days now. Starting ADE just immediately exits with no error message or any screen display. Tried all the suggestions above. Uninstalled/reinstalled 4.5.10, renamed My Digital Editions and allowed it to create a new one. Last attempt was to remove Adept registry key. No luck on anything. Will try installing on a different computer next, in desperation. Don't really want to, I like this computer.
Guys!
I just did a procedure here that worked!
I've installed the ADE 4.5.10 on my Windows 10 laptop a long time, and the ADE was always starting a blank screen (stucked); the computer was authorized a long time too. Also, when I tried to access the "Leitura (PT-BR)" menu (would be "Reading" in a EN version), next to the Help menu, the ADE just shut down.
FIrst, I removed the program ADE 4.5.10 from Windows, and installed the ADE 3.0, available on the website, but I got the same error as stephaniel (Jan 10th 19), when trying to open an acsm file; the "check activation" error.
Then, I installed the ADE 4.5.10 back to Windows, removed the authorization (of my laptop) and authorize the computer again (both on ADE 4.5.10). It didn't work.
Last, I removed the authorization for my laptop (on ADE 4.5.10), and restarted the ADE 3.0, that started without the authorization, and authorized my laptop on ADE 3.0. Finally I could open my acsm files withou any problem.
Resume:
1-) Remove the computer authorization on ADE 4.5.10
2-) Install ADE 3.0
3-) Authorize you computer (with your Adobe ID) on ADE 3.0.
4-) Open you e-book (I was using an acsm file).
Hope it works for you too!
Is there anyone who works at Adobe who moderates this part of the forum and can tell how to get help with this problem?

Hello, did you find out solution yet? I have the same issue, can't fix so far.
Hello,
I have the same problem. My books are not downloading accros my Iphone and Ipad. How do I go about fixing it?
The books I have are pdf downloads from website. Such as archive.org and others. They do sync across iTunes library though.
I'd already de- & then re-authorize Adobe Digital Editions countless times. When attempting to sync library book(s), it sometimes says "reader for PC has stopped working" or syncing goes on long time but when open e-reader, new book(s) not downloaded or imported. What am I missing ?! HELP PLEASE !
I have an account with Next Step Prep which required me to download Adobe Digital Editions. I initially downloaded to my computer which has been running slow.
I tried to access the books from two other devices since Next Step‘s email said it would be accessible from multiple devices. However, I am unable to download any of the books. It says it is being used, which is confusing.
Please help! I have paid a lot for this study course but now I’m at a standstill! From the forum it looks as if someone else’s was reset pretty quickly!!
Did you get a resolution yet?
Digital Editions is not my centre of competence, but I may call for assistance using a different channel if you do not get qualified help via Contact Customer Care !
I am having the same issue.
When signing in with my Adobe ID though Adobe Digital Editions on the iPad (not sure if other platforms work)I receive the error, "Username or password is incorrect," even though I can sign in with the same username and password on Adobe.com, Acrobat, and Creative Cloud.
Can I use the ADE library separately to stamp the page numbers in an EPUB.
I mean is it an open source library, that any one can use?
I am trying to access an eScript on my iPhone. I have it on my iPad. I had reset my password and I keep getting an error message that the file is on another user. Adn then I tried to open it in Bluefire and it wants me to log on in the additional user. Please advise.
