I've been trying to get on and play insurgency with you guys, but every time I join a server, the game crashes and I get this hl2, send or don't send crash report window. Sometimes I also get a strange runtime error window.
i only get that some times when iv had ins minimised and open it again. you could try changing the DX it runs at from launch options( not sure what it is you shall have to find out) if that works then change the settings within ins to lower levels so its less stressful on your PC.
hope that helps
