So about this game VOX

I just use SAM when I want to farm cards, because it never crashes.

Go into your steam folder and manualy delete the game and re-install it. That worked for me. The game still crashes a lot and is unstable

I've never had an issue with VOX and I've put more than 50 hours into it since it's initial release (ignore steam time, I got it direct from Steve way before). It's a fun little project he's got going, have you tried contacting the dev on Twitter? Steam? IndieDB? He's usually very responsive.
