Game doesn't launch

When I launch KF2 I get the error in the following image

I've closed all the programs I can think of.
Plus, I've followed every instruction in the " Killing Floor 2 Support" post. Meaning I did "On that note, two general "fix alls" that may help you are to try the following:
Verify Steam cache. Right-click on KF2 in Steam Library > Properties > Local Files > [Verify Integrity]
Running the .exe redist files located in your SteamApps/common/killingfloor2/_CommonRedist location
Update any device drivers you have to the latest available
Delete your documents/my games/Killing Floor 2/ folder directory completely
Disconnect USB controllers and other HID devices except for keyboard and mouse
Restart Steam client
Launch Steam (or set the game .exe) to launch as an Administrator
Turn off DxTory

You will also want to try adding:
-dx10
to your launch options via Steam.

For those who have the 0xc000007b error we are doing further investigation on this. However we would like users to try reinstalling/repairing the following:

VC C++ Redist: http://ift.tt/1MPxgEr x64
DirectX: http://ift.tt/1fC9MDZ
.net: http://ift.tt/1MPxiw7

We have also seen some cases where doing a clean install of the PhysX driver (uninstall completely and reinstall the latest: http://ift.tt/1fC9ME2) has helped. "

In addition to that, I tried running the game in every possible compatibility mode in admin mode and without. Also obviously tried to completely uninstall and then restart the computer and then install KF2.

I'm really running out of ideas...
As much as I know my specs are above the minimum.
So....any suggestion?
I would really like to send my logs to Tripwire but idk how can i do that.

My specs are: Core2 quad 2.5GHZ
Ram: 4 GB 1333MHZ
Graphics card: Nvidia Geforce GTS 250
Running windows 10
