You probably did miss something, but the rules on this forum are clear and unambiguous. We can not provide specific instructions for DRM removal. Full stop. You will need to post a query where you got the original files and get help from there.
That being said, this does work and is straightforward once you get the pieces sorted, so have confidence and you'll get there.
