I'm trying to play the Dark Brotherhood: Continued mod from http://www.gamesas.com/?showtopic=873715. However, it's not working! I download the mod, and I extract the files using 7-Zip, and I can even activate the mod in the data files when I start up the game... but when I talk to Arquen, NOTHING HAPPENS!

I even looked in the Construction Set, and I could find no quest that was out the ordinary, no NPCs that were different that might be the randomly-generated victims, and no additional cell that wasn't in the original master file (which the mod will need in order to store the victims until they're ready to be used).

What am I doing wrong?
