Can you change what it says on the pitboards?

i just bought this game, and its already glitching up like mad, i deleted some big files from my personal folder (wich i now cant get back) and it didnt do anything, i deleted all my screenshots, i killed the resolution and its still unbarably slow, what gives? for $40 this game has some potholes

Its still not working i typed /namedemo ______ and it doesnt show up AT ALL

I have a mac so i had to buy an application called "Crossover" and when i deleted the demo of that game, the MX Simulator application went with it by accident! FFFUUU...how do i save my $40 worth of an awesome game
(ps. i still have my personal folder, if that can prove that i did buy it!)

Thanks!

How do you get white numbers on a black backround?

How do i record more that 1 race, cant you save different recordings so you can have more than one? If so, how?
