Im sure other people are having the same problem so..
Whenever they put out an update I am unable to launch the game.
So after every update, I have to delete the game folder and extract the Darknessv3.rar and Updater.rar again.
Once you do that, run the updater and let it patch the game again and you should be able to start the game after it updates.
Thats the problem I have, and im sure others are having it too so hope this works for you!
