No error message.
The game runs just like normal (fullscreen) with windowed mode ticked in the graphics option, lower resolution than my desktop resolution and restarted the game.
I did choose older graphics drivers just in case it worked but it is still the same, even the black screen in MoBo after I tried to import a screenshot still exists.
But as I have found, someone had the same problem as far as my black MoBo screen is concerned, and his solution is to use XFire to take screenshots, so I tried this solution and the screenshots get imported into MoBo just fine for some reason. A little tedious but at least I am able to use MoBo with this method.
