Starting Problem
Hello, so i played the Game for 5 Hours and i was in chapter 6 and now my detection program blocked the SashiroLaedrum.exe and deleted it and now im not able to start the game anymore and Steam cant install it new because it says the the file is blocked. What can i do ? I cannot give it back because im over 2 hours and i want to play it till the end.
