Problem connecting to servers and playing online in Killing Floor 2 (Killing Floor 2)

Hello everybody. NEED HELP. There are no more words, I just don't know what's wrong with KF2. To begin with: 1) The launcher is not the same as I saw on the video on YouTube, the servers that are there, about 20 pcs are not updated and do not enter any one, the game enters and nothing happens, or it throws an authentication error (authentication failed) and I shaking what it is. This is the penis of a 40 year old unmarried woman. 2) In the game itself, it does not find a server, and when choosing a server search, specific, well, somehow, I don’t remember it, it also throws out a window notifying that a server with such a request was not found.
Tried:
disable protection
open ports
different resources
deleted steam_appid
patch from 1005 to 1008 manually
all drivers and graphic libraries are
SAVE!
