I have the same problem with the Black Screen (but Audio is still there) after the Cyberflix Logo. I managed to get "normal view" back with ALT-TAB'ing and return to the game. After some tries the game is back without black screen. Maybe this will help you too? It's not a perfect result but it could help you maybe like it does for me.
I even don't recommend to have any windows left open in the background because starting the game caused reduced size of some windows for me. Its because the game reduces the resolution of windows in the background.
The graphics issue appears to be resolved with the recent tour update - at least, with the settings that I have on the program, I can launch from Galaxy without needing to turn my graphics card off, so that's a plus.
My system doesn't appear to recognize the game as a separate program however, since I can't alt-tab out of it. I'd love to be able to get out of the game temporarily without needing to shut the whole thing down - I don't think the game launches in any sort of recognizable window for me.
