Steam KO not launching after I press start in launcher

[matysak]

Hi guys,

I started having this issue last week, before that I was able to play no problem. When I press start in the launcher nothing happenes, not even the anti cheat picture in bottom right appears, and the launcher closes. Tried deleting the game, downloading again and nothing help.


Anyone has an idea how to fix this?

Thanks!

I had similar problem and my solution was that I temporarily disable my anti virius program (AVG) when I start the game from steam.
