This log doesn't really doesn't tell us anything. What type of DRM?

[zmixnyc]

Sorry, what can I provide that will be helpful?

[ElleKayEm]

Where is it from? How did you download it?

[zmixnyc]

Adobe Digital Editions

[zmixnyc]

I can open the epub file on an old computer and use "DeDRM 1.8" app and read it on that computer - but when I put it in my eReader is cannot be opened.

[ElleKayEm]

Is ADE that you used to download it on the same machine and user as calibre with DeDRM? Is it authorized with your Adobe ID?

[zmixnyc]

Yes it's the same machine and user. Do I need to authorize Calibre (or the DeDRM 10.0.3 plugin) with my adobe ID?

[ElleKayEm]

No, I meant is Adobe Digital Editions authorized with an Adobe ID?

[zmixnyc]

Yes ADE is authorized and has no problems downloading and fulfilling the epub book

[ElleKayEm]

Alright, let's try looking at a log of adding the book to calibre: https://github.com/noDRM/DeDRM_tools/blob/master/FAQs.md#i-cannot-solve-my-problem-with-the-dedrm-plugin-and-now-i-need-to-post-a-log-how-do-i-do-that

Thank you for the advice, here is the resultant log:

This log shows the book is decrypted. So there must be something about it that your ereader doesn't like. Can it be opened with the calibre ebook viewer?

[zmixnyc]

When I try to open it in Calibre 's ebook viewer it generates the error pasted into my original post..

[ElleKayEm]

Oh, yes, sorry. There seems to be something incorrect or at least something unusual about the structure of that book. But the issue doesn't seem to be DRM.

[zmixnyc]

What is particularly strange, then, is that it opens just fine in Calibre 3.48 on my old macbook.. any ideas?

[zmixnyc]

EDIT: I opened the book in Calibre 3.48 and "converted" the original .epub to .epub - that version opens fine in my eReader.. strange, but 'solved'...?

[ElleKayEm]

And that definitely confirms that DRM wasn't the issue since you can't convert a book with DRM.

[zmixnyc]

Still wondering why it does not work in Calibre 6.14?

[ElleKayEm]

Don't know. Guess the calibre viewer is less forgiving now.

[zmixnyc]

I'll continue testing...

[ElleKayEm]

Since the problem isn't related to DeDRM, you can close this issue. You can still comment or reopen later if needed.

[zmixnyc]

Will do. Thank you for all your help.
