Infinite Flight Not Launching

Ok, so i downloaded the Infinite Flight last night for pc on steam. But when i go to launch it brings up a black screen with a white loading circle in the bottom left corner, after about ten seconds, it then closes, and stop running. Is this because we are only able to play at certain times, (i thought that was only for multiplayer) or is it something else. Please help?

Same thing happened to me man. Initially this was the case. Then I was able to get into the game, but the game didn’t fully render (spartan was missing his legs, etc.). Tried to join multiplayer, the connection kept being severed.
