This log clearly shows you have DeDRM 7.2.1 which won't work with calibre 6.x. Make sure you are loading DeDRM_plugin.zip from 10.0.3 and not mistakenly reloading the file from a previous version. After loading, close and restart calibre.

[sososimps]

Yes, I saw that info too. But I have downloaded Obok DeDRM and tried installing (and restarting the program) several times, but it's still not working. When I search my installed plugins for DRM it only shows the old one (7.2.1), but DOESN'T show Obok. It only shows Obok if I specifically search for Obok, but not for DRM. If it makes any difference, I'm on Mac Ventura.

[ElleKayEm]

Try removing 7.2.1, restart calibre, load 10.0.3, and restart calibre again.

[sososimps]

Ok, did that. Now it's saying:

This problem is happening with library books, which is my main source of books. Previously deDRM has always worked.

[ElleKayEm]

So you still cannot install DeDRM 10.0.3? What happens when you try?

[sososimps]

The second log above says "Successfully initialized third party plugins: Find Duplicates (1, 9, 4) && Kobo Utilities (2, 16, 6) && Obok DeDRM (10, 0, 3)", so it looks like it's installed. It just doesn't actually remove the DRM.

[ElleKayEm]

I'm sorry I was confused. I was thinking you were trying to use the regular DeDRM on Adobe DRM. You're trying to use Obok DeDRM on a book from a Kobo ereader or Kobo Desktop?

[sososimps]

I'm happy to use whatever works! Until last week it worked fine every time, now all of a sudden it won't deDRM. I only downloaded obok deDRM today in an attempt to solve this problem.

I've downloaded the book from a library, opened it in Adobe Digital Editions, and then opened the epub file in Calibre. That process used to automatically remove the DRM, but now it doesn't. Once the DRM is removed (so I can remove the embedded fonts), I then transfer the book to my Kobo via the Calibre desktop program.

If there is an alternative method that will work, just let me know. Thanks

[ElleKayEm]

Install the regular DeDRM 10.0.3 plugin then. DeDRM 7.2.1 would have stopped working when you updated calibre to 6.x.

[sososimps]

Sorry this hasn't been an easy fix. I have deDRM 10.0.3 installed, as well as the obok one, and it's still not working. I've tried deleting the obok version and restarting (and deleting both and reloading repeatedly), but that didn't work. Any more suggestions?

[sososimps]

Could it have something to do with the lines I've put in bold/ the last 2 lines???

Now that you have DeDRM 10.0.3 installed, let's see a log of adding an Adobe epub to calibre.

[sososimps]

Yay, it's working now!!! Thanks for your help.
