Halo has been not working for a couple months now. Every time I would quit a LAN game in it or join a network game, my whole computer would freeze (It's a laptop, if thats a source of problems). However,just recently, every time I tried to open up Halo: Custom Edition, I got this.



Yesterday, I tried to open it out of curiosity and kept getting this message. About the 4th time I tried to open it, guess what. It worked! I played a few matches on snow grove, having fun. I quit halo to get some of the new maps, when I got the "Halo has stopped working" message. I tried clicking on it multiple times like before, but no luck.

I tried running it as administrator and it worked. But it went back to the oldest problem where my computer freezes when I try to do anything with the game.

Any help?

try uninstalling then reinstalling the game, just backup and any needed files

I found out the problem to the "halo has stopped working" message. But now I still have that problem where it freezes whenever I try to quit or start a new game in a map.

Try running it in Compatibility mode for XP.

Right click the Halo CE shortcut on your desktop and go to the compatibility tab.

Also, since your Vista, make sure you also check the "Disable Desktop Composition" and "Disable Themes" check boxes. I don't know if I got the last one right, I'm using Linux :D
