TOPIC:

Ive tried everything.I extract them,click on my game and still nothing.Maybe my game is installed in the wrong place?

The self installs go to C:\Games\Infogrames\Dirt Track Racing2\data .Sometimes you might have to remove \games\ from the destination address.

if you know how to follow the path
my comp - c - games - infogrames - dirt track racing 2 - data

inside the data folder create folders named "cars" "tracks" "skins"

then you can unzip everything right to the desktop and make sure that you are putting it where you want it inside the game
