Maybe I am doing something wrong. When I double-click the UE4 shortcut, the NC Launcher load. After clicking the play, the game load but stop before seeing the b&s graphic and then nothing happen.
When going into my events viewer, I see the app went into an error in win10x64. The part that confuse me is that It took 2-3 tries yesterday but eventually loaded, seems it's angry at me today and I'm not so lucky.
