So I just updated by dying light mod manager to the new .11 update and I tried to open dying light (and the location of dyinglightgame is all correct and everything) but it would not open. When i try to open it Via steam it simply won't open. It keeps telling me that it is opening dying light over and over without actually doing it. Also I tried to install a mod before the update in .10 and the mod undid some other mods but the game was working fine. So I tried to delete mod manager .11 and it says I could not because Aut2exe had a file open and i need to close it. HOW DO I CLOSE IT HELP PLEASE.
