I can't get cached music to play.

Hello, I am new to Twine, and have been trying to get music playing using SuagarCube.

This is what I've got:

<<cacheaudio "Crypt" "E:\Music\Crypt.mp3">>

<<audio "Crypt" play>>

You are Beorht, the mighty Bandit. Your legend lays before you, currently it reclines flaccidly but with some effort you could inflate it to proportions more appropriate to someone of your grandeur.

The music just won't start. Any help is much appreciated.
