Game crashes after loading

[andrrw]

I have 1 sound mod, 5 addon cars, 1 addon map, and 1 rim pack.
After I add another addon for example a car, when ever I try to load in the game, after loading my game just crashes, but when I remove some of the already installed mods, it works. Is there anyway I can add more mods than just 8 mods? Also what should I do with the folders called patchday1-26ng and mp folders?

You need a gameconfig.xml mod.
