I didn't make it!
When I star a Multyplayer or join one, and starting the second level.
maybe u should just reinstall teh game. And if that doesn't work, maybe u need to reformat the whole comp.
This could be a number of problems. -Insufficient RAM. Can be a problem with 256MB or less. -Corrupt files. Try reinstalling. -Total Windows f-up. Reinstall Windows. -Graphics issue. Download the latest drivers for your graphics card, or get a new card. Hopefully it's just bad software, and a reinstall will fix it.
