Just wanted to say, the kmzpub version (50 megs rip) seems to have the .exe hacked and messed up; the first level, instead of the Jungle, is North Korea (which is supposed to be the third level), and it'll crashes several seconds once the level starts (even stranger that the pause menu map still showing stage 1 map). Tried the demo version in the same computer (Windows 7 BTW, plus dgVooDoo) and works flawlessly.
I guess the iso version is the only way to go.
