thank you for replying to me! No, I am using the version that is available on Steam. I have to redownload the version here? and if so, will my save game still be available or will I have to start a new game? thanks again for the help!^^
If you're on Steam, you don't need this version and you shouldn't need to add the file to the game folder. Steam adds DLC files automatically, you just have to let the game update on Steam.
