KF Killing floor crashes on starup or multiplayer doesnt work

I used to play KF normaly few days ago, until I wanted to fix random crashings, that I used to have. After messing with some settings (read that you should mark this as true http://prntscr.com/fqp9v2) game started normaly, but if I tried to go into Fullscreen it would instacrash (I used to play on FC all the time). So after some more reading online and messing with the files game wouldnt start at all (after launch would bring up an error message that the game is not responding). Again did some reading and changed the compatibility mode to Windows7 and to start as Administrator and it started without crash, but if I went to multiplayer it would say that "Steam needs to be in online mode and it needs internet connection". How to fix my game?

If you are lazy to revert all changes or dont remember what you did - just delete killingfloor.ini and start the game.
