Calibre won't open one particular Kindle Unlimited purchase.

Hello

Today my Kindle for PC app auto updated to the latest version (even though the auto update box is unchecked). Seems this happened to many people but that's not my problem as I just reinstalled K4PC v.1.17 and reregistered it.

However, one of the Kindle Unlimited books I downloaded, when imported into Calibre, won't open in the viewer saying it's DRM protected (which shouldn't be the case as I have Kindle Unlimited on my account). I'm using Calibre 64bit on Windows10. And the other two KU books I downloaded after, DO open without any problem.

The KU book which won't open is "Ruth Bader Ginsburg: The Biography by University Press".

Anyone have any ideas why it won't open and how to fix? I've already tried deleting/removing/returning ... ie getting it off my reinstalled K4PC v1.17 app/device/deleted from my Amazon content and redownloaded it to the K4PC v1.17. There's no problem opening it in the app and importing the file into Calibre but still Calibre's viewer won't open it. When I go to Edit Data on the book, I can see it's a AZW file.

Before, whilst it was the latest Kindle app version, it actually created its own folder named as the B00 number and within that it the book file sad MD beside it. Whereas, now the Kindle app is v1.17 again, as usual it doesn't create its own B00 folder and just put the book file (showing as Kindle Content) in the My Kindle Content folder, with the same named APX file ... same as it always has.

Is it anything to do with it firstly opening in the upgraded Kindle app?

Anyone got any ideas on why Calibre won't open it in the reader and how to fix it please?

Any suggestions greatly appreciated. Thanks.

Thanks jhowell. Sorry, I didn't think I was asking anything wrong as the book belongs to me under my Kindle Unlimited membership and I don't even know if it is a DRM problem as the other Kindle Unlimited books open normally.

UPDATE: I've solved the problem now anyway. As well as reinstalling my K4PC v1.17 ... I also uninstalled the update to Calibre (to 5.3) and reinstalled my previous version of 4.23 and the KU book which wouldn't open, does indeed now open. So, all sorted and hope it was ok to post this update here. Thanks.

You do not own that book on Ruth Bader Ginsberg. You are only borrowing it. It's the same as borrowing from Overdrive. You don't own those either. So discussing removing the DRM from Kindle Unlimited eBooks won't happen here or at the Apprentice Alf blog.
