Just black screen for me too on three different Macs. Windows shows dialogues but there are no graphics either. Music plays in the background.
iMac12,2 / iMac10,1 / MacBookPro8,1 (High Sierra on all)
Windows 3,1 GHz Intel Core i5, AMD Radeon HD 6970M 1024 Mt (Windows 7 and 10)
Switching Movie/Game has no effect.
