Anyone that still has this problem!
There seems to be a mad misse code on either steam or ST part as this happens when both aren't on your local drive.
So in short FIX you need to have both steam as well as saints row on C:/ or any other hdd that is actually inside the macine. If either is on a usb drive it will end up in the gray box for launcer or black screen before the menu.
Atleast that's what i worked out for my system.
