HELP!! Starcraft Crashing after briefing!

[Elrohir]

Ok, I made this map and when I start up starcraft and try to host it on the internet to test it with my friend when he tries to join it says 'unable to join selected game'. So I try to test it myself offline. As soon as the game briefing is done, starcraft goes black and crashes. Now I use xtra editor and starforge about once in it, I checked and there are no units out of bounds and no buildings that crash sc. I spent alot of time on this map and have not even been able to play it
