I can't make this work.
I've just bought a drmed ebook from B&N, downloaded it and opened it with their reader for PC.
When I run ignoblekey.py (version 2) all I'm getting is a pop-up window saying "Error: Problem decoding key; unexpected DB format?" after a few seconds.
EDIT: My clientapi file is: ClientAPI_v012.db
EDIT: Solved. I just removed the ClientAPI_v012.db, ran B&N eReader and logged in. A new clientapi was created and everything went fine.
Thanks!
