Unity stop working!!

Hi guys... I'm really, really worry about this!

I'm making a simple videogame using the Kinect for Windows device. I was working on my game.. I was just coding! Suddenly when I hit play.. Nothing happened! I mean, any animations was reproduced, my character doesn't move... The thing is that I have some scene (6 in total).. In 5 of them I'm handling everything with the Kinect Sensor (those 5 are the Scenes with the problem).. But, weirdly, in the other one it works!

I don't know what to do.. I have unplugged the device, I've restarted my laptop but nothing seems to work. :(

PLEASE.. I need help! I HAVE to continue developing my videogame!
