Removing Barnes and Noble DRM

[mtngr1]

Okay, so I've read that Barnes and Noble has changed how it's key is working so its difficult now to remove their their DRM.
Changes at Barnes & Noble
In mid-2014, Barnes & Noble changed the way they generated encryption keys. Instead of deriving the key from the user's name and credit card number, they started generating a random key themselves, sending that key through to devices when they connected to the Barnes & Noble servers. This means that some users will find that no combination of their name and CC# will work in decrypting their ebooks.

There is a work-around. Barnes & Noble’s desktop app NOOK Study generates a log file that contains the encryption key. You can download NOOK Study
Can't find a copy of nook study. I just bought 4 books today, thinking that it worked like it used to last year, and now I don't know how to remove the drm so I can read them on my other Tdevices. Help,Please
TIA
