Downloaded the game at the first menut here is no background, when i chose myc haracter still no background it's just black, and when i play there is no floors or wall i just walk in air and my game crash after a couple of seconds of playing, i uninstalled and re-installed my game and still the same thing

(PS:I downloaded it through steam)

It might just be my computer fucking with the game tho, my computer is starting to get old and crappy, makes VZZZZZZT sound when i open it, anyway the topic is not on my computer...
