Conversion not working any more....
I use Calibre to convert my kindle books and Adobe epub books. All has worked flawlessly for a couple of years. However, just recently I have followed the exact same procedure as before but I am getting error messages that the books are DRM protected and can't be converted. Is the procedure no longer valid? I have the latest 64 bit Calibre and the latest Tools. I have removed and reinstalled Calibre and the Tools to no avail. I have tried running each plugin on its own again without success.
What am I doing wrong?
