Killing Floor 2 won't start, I have tried everything and I still need help!

[Help_me_KF2_doesnt_work]

I have bought the KF2 digital delux edition and can't get it to work. Everytime I press play the little black box apears that says "now starting killing floor 2" and then nothing happends other then my profile turning green for a moment and then back to blue.

I have tried the following things:

-I updated my drivers
-I restarted Steam, reinstalled KF2, restarted my PC
-I used the verify game cache option in steam
-I tried running it as an admin
-I run all the Commenredist applications
-Deleted and reinstalled Nvidia physics
-Deleted my docs/my games/killing floor 2/kfgame/config folder
-Deleted my client regestry
-Disconnect USB controllers and other HID devices except for keyboard and mouse
-I added -dx10 -windowed to my launch options via Steam.

My specs are:
AMD Radeon HD 7570 Graphics card Intel Core i7-2600 CPU 3.40 GHz Processor 16 GB RAM and a 64 bit system software

Nothing I tried has worked so far, any ideas? Oh and thanks for the help in advance!

Okay I've found a solution okay so you go to steam go to game library right click on killing floor 2 then click on properties after that go to to local files then click browse local files after that go click on commonredist then you redownload all four of those file you see after that restart ur PC and that should work at least it worked for me tell me if it worked
