"Key cannot be null string" error

 

Hi guys,

I am trying to remove the DRM for my epubs.....

Have input my cc number and name exactly as it was found in the B&N website, but when I output the file, it still shows the "Key cannot be null string" error

Can anyone help?? :confused:

What DRM removal software exactly do you use? Do you have Python (Active State Python v 2.X 32 bit), PyCrypto and OpenSSL installed?

Hi Stream,

Thanks for the reply.

Managed to get it working now. What I did was to uninstall everything and do a clean install of everything...maybe the software got confused after I tried to install too many things yesterday

Python version: ActiveState 2.7
PyCrypto version: 2.3

I'm using the ignobleepub and ignoblekeygen method of converting the files (at least for now)
