Any ideas, can't test without the editor

Right, whenever i go into the usual wc3, click my map, then the start button game, wc3 tries to open it, then straight after closes it, iv tried many times but to no success.
It works fine if i open it up with the editor with vJass, grimore etc.
I'v got a video i took on fraps to show. (Actually no, its 130mb, for less than 30 seconds of capture.)
Anyway, can't really post much more, the map is quite confidential at this time, as im making something i dont want anybody to know about yet.

So, the question is, what could cause this?

Nevermind, there was a syntax error, forgot that it saves with errors.
