Hi,
Every time I start Arma 3, after getting to the splash screen the game freezes. When I close the game in Task Manager, I get the 'Application Hang' error. This happens in the stable, dev and profiling versions. I don't have any mods installed and other games seem to run fine. Occasionally, I can get through to Singleplayer or Multiplayer missions, the game runs fine for a bit, but then freezes up again.
