Libation VS BookLibConnect

You can use software like Libation, AAX Audio Converter or inAudible to decrypt Audible books.

I removed the DRM from the audible books using Libation: https://github.com/rmcrackan/Libation

Sounds like a bug. I hesitate to say how to fix this issue with the usual means since it's already in a not usual condition. If you'd like to open a ticket here, we can help.

Author of Libation here. Sorry you're having trouble. Apple wants us to pay an annual fee to be on their safe list. I have neither the money nor inclination to pay for their protection scam. Here is help for installing on Mac. If you're still having trouble, please open a ticket here and we'll be glad to help.

Definitely Libation. Works on Windows, Mac and Linux. Free, or donate. Download here: https://github.com/rmcrackan/Libation/releases/tag/v10.4.1

There's still a webplayer if you don't want to install additional tools, as well as BookLibConnect for downloading the files and AaxAudioConverter to jailbreak the books and convert them into a format you decide.

Downloading/exporting: BookLibConnect

I recently updated AAX Audio Converter, it now offers hints and links to its companion Book Lib Connect. You can see Book Lib Connect as a replacement for the now defunct official Audible App for Win 10. The long term goal is still to integrate Book Lib Connect into a revised AAX Audible Converter, but I don't have found the time for that yet.

And, of course, there is also AAX Audio Converter with its companion Book Lib Connect, to complete the picture of the most popular Free and Open Source tools in this area.

I split my books not only into chapters but into even shorter tracks, about 5 minutes each. To achieve this, I created AAX Audio Converter (and later the downloader Book Lib Connect as its companion), which has become one of the most popular tools in this field.

Of the Free and Open Source converters to plain audio (motto: "Use any audio player you like"), my little but rather popular AAX Audio Converter was cooperating perfectly with the official Audible app for Win 10, including support for named chapters which came as separate json files. However, AAX Audio Converter still cannot download the books itself. So I started on a downloading option. It was just by chance that I released the first version of Book Lib Connect just the moment in January when Audible announced the discontinuation of their Win 10 app. Book Lib Connect downloads and decrypts your books and also exports them for further processing with AAX Audio Converter with all its many tailoring options. From the perspective of AAX Audio Converter, Book Lib Connect serves as a substitute for the Audible app.

First of all, you are aware that there are Free and Open Source alternatives for converting your Audible books to plain audio? One rather popular example is the pair of Book Lib Connect and AAX Audio Converter which I created>! (shameless advertising)!<.
