Cannot get Bugatti Veyron Super Sport

I have beaten the Bugatti Veyron Super Sport (most wanted #3) in the race, but it got away before i could take it down, so i continued playing the game, beat and shut down the Pagani Huayra (most wanted #2). In that time i never saw the Bugatti Veyron Super Sport so i went back, and beat it in the race again for another 12000SP and then I shut it down, But on my most wanted list it still shows as not beaten, and it is not in my car list! It stayed where I shut it down, and no matter how many times I tried, I always get the same result! I tried reinstalling the game, restatring the PC, and repairing game data and nothing! Any ideas?
