Need for Speed Underground 2 help

Ok, I have beat everything in level 1. After the last race no more races appeared on the mini map while in careerer mode. I still have many races to finish in level 2. While in careerer mode I access the pause menu, and go to my garage. In there I load the world map to see what races I havent done. So I raced all of the rest and I didnt get paid anything for it. It didnt even unlock any new things. Even after that no races show on the mini map. I found out that I have only completed 36% of the whole game. Whats the deal?

have you done all the outrun challanges, i dont have the game, i was playin at my friends house and thats how i got all his money, i guess you should look online for help like at websites and stuff
