Light grid bug

Hey guys! I am having an annoying problem related to the light grid. When I am collecting dots, somehow cod2 crashes (it didn't in my old PC with windows XP, I've got win7 now and I run Compile tools as admin, with xp compatibility mode etc etc). The thing is that when it crashes, the .grid file doesn't create :mad:. I've got a big map almost finished, and cod2 crashed twice when I had collected like 1000000000000 dots :mad:.

If someone knows the reason of this error, or any other way to make the damn light grid without being like Pacman, I would appreciate it :rolleyes:

Thanks!

Maybe just install XP in VMware?
