Does the Menu load? If the game crashes when you try to launch a level or the tutorial, it is not a crash but a loading screen. Try to wait a few minutes, if the game still don't work, give me more infos about your OS and internet browser so I can see what I can do :)
Edit: I made 3d load on menu, so now it doesnt take so much time to start a level but you have a black screen and a strange sound when the game starts. Just wait, it's not crashing, just loading ;)
