Literally unplayable due to crashes

Insurgency is such a great game but it is impossible to play, because it crashes CONSTANTLY. I cannot play co-op or versus for more than 15 minutes without the game crashing. This is completely ridiculous and unacceptable. Why was it released in this state? I can't believe I paid $40 for a game I can't play.

and just to add, I really enjoy this game. It's immersive, fun, and tense...but it doesn't work. The crashing every 15-20 minutes just ruins it. I'm hoping they fix this soon, because it could really be a hit.

I bet you're so happy you blew that much money on a game you can't play.
