I must instal some new soft for game?

It's crash in fullscreen and windowed mode?

I can`t switch the window options. When i start - the game is fail. Launcher do not work.

Delete your OST_Game folder inside:

C:\Users\USERNAME\AppData\Local

That'll reset all settings for the episode (graphics, language and in windowed fullscreen mode.)

Can u see that?

Got the same problem,

When I launch the new build, it crash with fatal error : "The UE4-OST_Game Game has crashed and will close" "Fatal error!"

I've deleted many times the "OST_GAME" repertory in user/local/, nothing change
I've uptated all my drivers and still the same things, I work on win10 and must admit that I'm lost on how it works. The build before 1.x still working, Joyous Reunion still work too...
