Bioshock

So the Bioshock package finally arrived on i think Monday because my dad ordered it. He opened it up and it was the Bioshock book and so we were a little disappointed so he took it back and got the game. So now we are happy and so we set it up yesterday. Apparently when you move the mouse its not smooth and its really annoying so now we need to fix that problem. We have no idea how but we really need to figure out how because it is really annoying and i don't know how we are supposed to play the game with the mouse all jacked up like it is. My dad tried fixing it yesterday but couldn't so hopefully he can fix it today.
