I've been able to play before, but now the game refuses to start up. I launch it (through Steam or the Cloudlands.exe file itself) and it brings up SteamVR, but Cloudlands closes almost immediately and doesn't display any error messages or anything like that.

I think I saw the Unity crash screen (with a red exclamation point) once, but it was so fast I couldn't read anything.

I really enjoyed playing before, and would like to try some user created maps, but can't get the game to start to even give it a go, please help.
