Yesterday after I sent this question, I downloaded GameEx to see what it looks like. I stored it in a different location than my PinballX.
When I was done checking it out, I uninstalled it.
Now when I run my PinballX, all my videos (that run on the menu showing the game) are gone and I only get a black screen with the wheel art.
Did GameEx delete a key in the registry or turn some other function off in the settings setup wizard?
I did go back and have PinballX create new videos, but the screen is still black.
Is there a simple fix?
