many, many, many people are having this problem, me included. no one has found out why this happens but its really fuckin annoying. i hope someone fixes this soon. just know your not alone.
i get the exact same problem, it opens for like 2 secs and then shuts down with no error message or anything... if someone has any solutions please inform us...
one thing I have found with the tutorial map is that it has no textures/materials assigned to it, coz when I loaded the tutorial map into 3dmax it said the materials were outdated or something.
might be that?
well i have another computer on a LAN network with my PC... and i simply COPIED the entire HEK/HaloCE folder over the network and sapien works fine on my laptop on the network, but not on my PC... strange.
