I didn't do anything unusual, it said to move the wooden tree trunk by pressing the interact key (E) and I pressed that button and the arrow keys and every othe rkey on my keyboard and the escape key etc and the game was unresponsive. the only thing I can think of on my end that might possibly be fouling things up is that I have an X-BOX 360 USB controller plugged in. I'll try unplugging that and seeing if that fixes anything.
