Try removing media_play and see if that helps. I have similar problem with one of my projects that I can't play on a desktop; the game freezes as soon as the music plays through media play (atleast I suspect that is it, have to double check that, could also be some other sound or something with level load).

If that is indeed the problem, perhaps altering the music file or use snd_play. Don't quote me on that though, I am a newbie when it comes to sound/music stuff.

-edit, if that doesn't work try commenting lines or blocks until the published project works. Or e.g. add long waits at several spots that you suspect that the problem is. Also check if warn_level is on.
