That's great, but it's not working for me either. :S Same issue, stuck on "waiting for game."
Naturally followed troubleshooting steps as always. Windows Defender deactivated, running Windows 10, Steam is active, HD version, alt-tab fix tried.
Game updated on May 5th.

Only me experencing that when i turn on "One Hit Kills" the screen turns black and you can't see anything at all? The sounds and the game itself is still possible to play but there is just a black screen.
Use this option either later in the first night when you already have shot a good amount of zombies or enable it in the second night, from where you can keep it enabled the whole time.
The game needs to write a few values first until this option can kick in and does its work.
