I completely uninstalled the drivers with DDU, I went back to about 10 different versions (including the one she had originally), I tried changing the config to DX11, I tried deleting the config and letting the game create it new, custom driver install with only the actual driver and the audio driver (we plug it into our TV at night for Netflix and what have you so I need HDMI sound). I have tried all of the things that don't work.

I can still see the cursor, and the music plays, and I can interact with the game seemingly no problem, I just can't see anything except the cursor. So, I installed the latest driver and now when her game starts up the screen is black. My wife has been crashing every once in awhile, unfortunately I can't recall the error she was seeing, but some googling brought up it might be a driver issue. I prefer working over not working, but if there is any option that might help getting windowed mode working again that would be great. I guess she used to run it Windowed and Windowed Fullscreen so she can price check items without having to ALT+TAB out completely.

EDIT: Fixed by changing to full screen in Config file, but.
