Kobo Download Error

[Aleron Ives]

I just bought a Kobo book and attempted to download it with ADE as usual, and I get the error:

E_ADEPT_DOCUMENT_TOO_SHORT

Various web sources indicates this means the book file I'm trying to download is corrupt. Do I have to contact Kobo support for this, or is there another solution?

It's probably worth while reaching out to Kobo

Last time I ran into that error, we needed to re-authorize ADE on the computer.

[Aleron Ives]

Thanks, I guess I'll have to research how to do that and contact Kobo support if it doesn't work.

I removed my authorisation and authorised again, but the error persists.

So, I just chatted with the Minerva chatbot and an agent who claimed to reset the license for the book and advised me to update ADE before trying again.

Since I'm using Linux, I don't want to risk breaking my currently working version of ADE 2.0 for an update that might not help.

Has anyone else had a license reset that solved a download error before? Should I try to download again with ADE 2.0, risk updating ADE, or potentially switch to the Calibre DeACSM plugin and give up ADE entirely?

*edit*

The error persists on ADE 2.0, even after deleting the Adept key from the registry and re-authorising yet again.

I tend to recommend the latter. I once used ADE 4.x successfully (you can install it easily via winetricks). Nowadays, I only use the DeACSM plugin (but not often, since most of the epubs are drm-free in Germany).

Maybe try downloading with the Libby website?

Edit: I mean use the Libby website to get the ACSM file, and then use ADE.

Fyi one can easily backup and restore the ADE activation from the device. Just backup the .adobe-digital-editions folder. In fact by restoring this to other devices it avoids having to go through the ADE activation steps.

It's a Kobo book, not a library book, so Libby can't help me.

I just bought a second book to test with, and I can't download that one, either. It appears something has changed on Adobe's end, and my ADE 2.0 installation doesn't work anymore.

I guess the next thing to do is to set up another Adobe account and try to configure the DeACSM plugin? Sigh...

FWIW, the DeACSM plugin can create an anonymous authorization for you as part of the (simple) setup process. You therefore don't need to set up a new Adobe account before installing it.

There's a clear and helpful Readme file included in the DeACSM zip.

The DeACSM plugin ought to be able to use your existing Adobe account. I certainly have mine set up with my original AdobeID

Yes, I saw that in the setup instructions, but are there any downsides to this? I don't really understand how the anonymous authorisations work, unless they're exploiting some kind of loophole in Adobe's security where Adobe doesn't bother to check that your machine ID is tied to an e-mail address before letting you download books.

Yes, but the README warns you not to do this, in case Adobe tightens security at some point and starts detecting and banning people for using an unofficial ADE implementation. Has anyone actually been banned for using DeACSM?

From a practical standpoint, I suppose it wouldn't matter that much if my existing account did get banned, since ADE isn't working anymore, anyway...

I haven't noticed any - unless you regard the fact that you can't add Calibre-downloaded books to your ADE library as a downside. I'm perfectly happy having them in my Calibre Library instead. I've been using it for a few weeks, with an anonymous authorization, and haven't noticed any problems beyond that.

I also don't understand how it works. But the fact that it does work is enough for me.
