Windows 7 Rage car races

[lostsoul65]

I won 3 of the races on the 2nd car down and it won't let me play any other races and then I went to Rusty and bought all the weapons I could and then went back to the sheriff and he said I need weapons. What did I do wrong or what do I need to do, I don't get it?

Did you get weapons for yourself or your car?
