Cross DJ Pro 4 loads to BLACK SCREEN

So I paid for my upgrade and downloaded Cross Pro 4 (Full Cross Version User Prior) and when it loads, there is NO GUI visible. I cannot see anything at all.
The tool tips show up if I hover over an area where there is supposed to be something, but there is nothing there.
I can get menus & preferences to open, but not correctly.
If i force it into Full Screen, there is a big black box over everything and the GUI is partially visible, but doesn't do anything.
HELP!!!
