I had this same problem yesterday around the same time. I attempt to join a server. The Arma3 splash screen comes up, then the screen goes all black/grey horizontal lines as it normally would while loading into the game. However, it goes no further than this. I can hear water splashing on the shoreline and I see the server running its script messages in the bottom left corner. Unfortunately, it goes no further. It just stays on this screen updating the server messages. I tried loading into a private server as well as the "official" ones with the same results. Ultimately, the problem was fixed and I got some game time in.
Today, I am having the same problem. I have validated the game files through Steam with a result that they were all OK.
Can someone fix this?
