So I uninstall the game and luckily I have slrr on a memory stick. Installed the game. All worked fine until the game started to crash when driving in city. On the racetrack, it worked very well.
Now I have the same problem and I almost know what causing it.

I got that game from a friend of mine. He installed a rim package to it, called Extreme package.
Error log said:

!Package conflict: multiple packages placed at the same location ( at parts\Extreme_Pack\scripts)
---

So I tried to delete it. The game won´t start anymore and after deleting that s..t it says again this:

!Script error
