I explain the steps that I followed if in some of them I found the error that causes me the failure: The steam game installs it in a separate folder created called "SteamLibrary". I can play it without error. After having it installed (it is 17.2-b27) I make a copy of the clean game. Then I download the "darknessfallsa17client-master" mod. I unzip it and copy and paste the three folders in the copy of the game made, to which it asks me to "cancel, omit, merge" and merge. In the game I try on a map of what there are already facts.And when opening skills to watch is when I jump the console and red puts me: "FormatException: unknow char" and I can not do anything.Sorry for my English
