Yesterday I was playing, but the game doesn't work anymore, it doesn't launch at all

I'm trying to play but the game just stays like this on Steam and won't start, does anyone know anything about this?

Ive just installed this game and cannot figure out some of the keys......D_UP, D_Left, D_Right, ive looked but cant seem to find a proper manual for this game, any help would be appreciated.

I've tried everything to solve this problem but nothing happens, any solutions?

things ive tried reinstalling drivers the physx uninstall/repair game folder / right clicked homefront / properties / compatibility / run with current version of windows any other solutions out there?
