When i put the .dll file in the rocksmith folder (i don't have steam rocksmith) and try to open it it simply won't start. In the task manager says that for a few seconds the game is running but then turns off. I can't play CDLCs because of this, any fix?

Purchase the game on steam. That's the only way it'll work, and that's on purpose :)

 

Not to mention that using a pirated game is against our rules that you agreed to.
