Title

Windows 10
calibre 6.7.1
kindle 1.17.1
DeDRM v7.2.1

I have an old computer that still works fine -- same versions of all the programs. But sooner or later that machine will die. I have never gotten DeDRM working on the new machine for kindle books. I believe it does work for adobe editions. But not for kindle.

Recently what happens is that the kindle file gets read by calibre quickly. Looking at the logs, it seems to think there is no encryption. But the mobi that ends up in calibre is scrambled nonsense.

thanks for any help!
