Black screen and no sound at beginning of launch from desktop shortcut. Unreal demo and other demo worked then nothing. Things i've tried: Driver update, Direct X update, CMD changes "BCDEdit /Set IncreaseUserVA 3072", deleted videos from install directory, complete Re install of game, resolution X Y from native 2560x1440 to 1920x1080 in UDKSystemSettings.
