Was the book downloaded with ADE on the same computer and user as calibre/DeDRM?

[MANLEFEU]

The book was downloaded from public library numeric document forùat epub yes on the same computer and calibre

[ElleKayEm]

If there is a saved Adobe key in DeDRM's customization, delete it. Restart calibre and re-add your book letting DeDRM automatically retrieve the key.

Hi, I just had this same issue, because i tried to remove DRM from another PC than the one that downloaded to .epub file. I tried to directly convert from the initial PC, and it works ! Thanks a lot :)
