Have you checked the console for errors? If there's an error, it will get stuck on the preloader.
Only warnings I receive:
** 8 Bitmaps packed successfully into 1 spritesheet(s).
Frame numbers in EaselJS start at 0 instead of 1. For example, this affects gotoAndStop and gotoAndPlay calls. (6)
Content with both Bitmaps and Buttons may generate local security errors in some browsers if run from the local file system.
I don't have any frame commands in my script though.
He meant the error console in your web browser, not Animate.
Although I'm going to guess that you're using Chrome.
Thanks, I'm using Safari and found the error.
