OK I downloaded this car set and am apparently doing something wrong. I unzipped all the files into my cars folder and the cars show up in the game. But the paint mapping doesn't fit the cars properly. I'm not sure what I am missing. This is afresh install of the game after being away for it for many years. There is probably something that I am forgetting to do to make it work. The cars that came with the game are all good. Only the ones from this set are not. Any ideas?
