Well firstly Steam is gaming engine to my memory, and many games run off it. Killing Floor is a steam game, therefore requiring steam to play online, if you have the patches for it.

If anyone is having the problem where your just playing threw a mission then all of sudden it goes to main menu and every time u try continuing game it repeats same mission over and over, i just downloaded the crack fix and works fine for me now, i had it on chapter 2 or 3
Crackfix: http://www.torrentz.com/c5ef3af653e846bb068650e4854c96f01c748725

How do i play it, i mounted it with daemon tools, installed it and now it keeps asking for cd key again and says its invalid now??
