Calibre Plugin 10.0.9 - DeDRM

[FuSi-ML]

Hi, I am using Calibre version 7.26 and downloaded and installed DeDRM version 10.0.9. I was able to remove DRM in one of the Kfx files by following the instructions in these forums: Add books --> Navigate to the Kindle folder --> select the particular book. However one other file i wasnt able to remove. The logfile shows the follows:

_**calibre, version 7.26.0

Can you tell me what I am doing wrong? Or is this new format not supported by the plugin yet?
Unfortunately amazon has done away with the download and transfer via USB option. So the only option is to choose the file directly from my kindle after downloading and adding it to Calibre to remove DRM.

Thanks a lot for developing this plugin and for the support.

This may be a question for @j-howell, the maker of KFX Input plugin. Let's see a log from when you first add this 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

I don't know what is going on with this book. KFX Input doesn't seem to be able handle it and so DeDRM can't do anything with it. I have not seen this before. I'd try re-downloading the book.

[j-howell]

The error message indicates that file main KFX file for the book is empty. That is likely due to a failed download by the Kindle. Remove the book from the device and download it again before importing into calibre.

Thanks a lot. I did just that and it worked. It looked like a failed download because before I redownloaded I tried to opent he book in kindle itself and it didn't work.
I really appreciate your quick response and prompt help.

Thanks @j-howell and thanks @FuSi-ML for reporting back that it worked.
