I have reinstalled my game after a backup of my computer and when I have done that, the sounds looks broken!

The central boss or the storyteller when you start the game doesnt work at all! That is so weird because the voice of the characters inside of the game works perfectly so I don't know why this is happening. And It is so annoying to play the game if the storyteller doesnt tell you the main issues of the mission and stuff like that

I have reinstalled the game and change the language several times but nothing happens

Thank you guys! And sorry for my poor english :(
