Okay thanks for that! Turning off code cave migration in Sophos works but I'm not really happy with this solution having read up on what Code Cave Utilization is. Perhaps smarter to only have it disabled when playing TS4? Just tested I can get the game going while I'm disconnected from the internet, so will do that until there is a more comfortable solution for this.
