... it gets stuck forever on the loading process between briefing and "Start mission/aircraft tree etc" screen.
the 4 squares rotating on the bottom right plays at constant speed indicating it's not loading at all.

if I force-stop the application and try again, the 2nd time the squares get froze and the menu actually loads after a long delay
the 3rd time and beyond it becomes normal.

Anyone having this kind of situations?
Seems to happen to me on other UE engine games too: loading the game for the first time since PC boot takes disproportionately longer. We're talking about 10 minutes of loading till in-game, that kind of "longer".
