Mouselook crashes program

I tried activating my first python script, mouselook, and when I finished the tutorial, it crashed the program. I have a hunch it may have to do with my file folder placement. This may not be related, but my yafray isn’t registering either. Also, as if that wasn’t enough, my game.exe won’t save and it crashes the blender program. I am running windows vista and blender 2.46. My other funcions work fine (modeling, animation, and in blender game) Any help would be great. I’ve searched all the threads here and noone seems to have the same question.

I downloaded the older 2.5.2 version of python and that fixed the problem
