I have currently tried for days to get Arma 3 multiplayer to work, but at most it will run for about 5 minutes, and then it freezes and I have to shut it down. Any mp games after that will then freeze on the loading screen after I select a team and hit play. After that, I have to restart my computer, where the cycle repeats again. Re-installing had no effect. If anyone knows anything about this or needs me to add more information, that would be greatly appreciated. Current version: 0.76.109065
