    hey, there still seems to be some error on startup, i can get in menu, but the game crashed when i try to change car, or start a race

    On my end everything is working fine :( I need more details ... what platform are you playing? I'm on Windows 10. Please make sure that all dependencies are installed as listed on the download page.

    Hello! I clicked on the .exe (I guess) and nothing happens, doesn't open any game, why?

    Hey, I verified the download and found out it was somehow missing files. I updated it. I should work for you now. :)
