What happens if you execute it from a terminal window?
That way any error messages will be visible.
What happens if you ruin it from inside IDLE or Pythonwin?
THe fact that you have a raw_input means the code should pause
at that point, if it isn't it probably suiggets a syntax error or
similar
in the code before that point...
