Whoops, sorry I didn't see this earlier.
Make sure Flash is updated. If you are running a current version, try specifying the application that opens it instead of letting the default program try to load it. I've used it on OSX, Windows XP, and Windows 7, and used IE, Firefox, Flash's own player, and even Gom's player to open this.
If you still can't get it going, let me know what operating system, Flash version, and application you are using to open it.
Actually, I should just go home and republish this on some other formats. Check back a bit later for that.
