DRM stopped working

I am using Calibre version 4.2. DRM tool removal 6.8.1.

calibre, version 4.2.0 ERROR: Loading book failed: Failed to open the book at /Users/caseemiller/Calibre Library/Georgia Lyn Hunter/Absolute Surrender (Fallen Guardians Book 1) (1775)/Absolute Surrender (Fallen Guardians Book - Georgia Lyn Hunter.azw3. Click "Show details" for more info.

If that's tied to an E-ink Kindle (not a Fire), then enter your Kindle's serial number into DeDRM's customization. Then restart calibre and re-add your book.
