De-DRM plugin not working for a precise book
Hi,
not sure whether you can help, but I'd like (as I did several times) to deDRM a .mobi file purchased on Kindle store, to be able to use it on several devices (and convert it to other formats too).
Although the plugin is correctly installed (it has worked with other books) it does not manage to unlock this one, and I get an error message instead ("this book is locked by DRM. To learn more...").
Do you have any suggestion? I'm using the latest Calibre version (2.44.1) for Mac.
Thanks in advance
Giorgio
