Re: How to remove DRM protection from B&N (Barnes & Noble) EPUB ebooks

If you get the "B&N User Key not found. Unexpected DB format?" error, you can try to remove the "ClientAPI_v012.db" file, then re-authorize BNReader with your account information. Alternatively you can use the key-derivation script (ignoblekeygen). Both ignoblekey and ignoblekeygen will produce the same output when they work correctly.

Also make sure you use the name from the Credit Card, not your B&N username.

If you need to remove DRM from PDB files, read the following thread:
Remove DRM from PDB ebook from B&N (Barnes & Noble),...

The books are ePub books. I have tried this several times now and still not working. From your comment (Also make sure you use the name from the Credit Card, not your B&N username.) it seems that I am doing something wrong.

How am I supposed to run this? I have done following things
1) Downloaded BN eReader for PC, logged in and downloaded my ebooks. I see them under "C:\Users\MyName\Documents\My Barnes & Noble eBooks\MyEmailAddress"
2) Downloaded and installed Python 2.6.
3) Downloaded "ignoblekey.py"
4) I double click and see the error "B&N User Key not found. Unexpected DB format"

What am I doing wrong?

I have Windows 7 PC. Also want to add that I have tried deleting ClientAPI.db file multiple times and that the file is always called ClientAPI.db - not ClientAPI_vXXX.db. File location is C:\Users\MyName\AppData\Roaming\Barnes & Noble\BNDesktopReader
