After Exporting my game, not working on windows 8??

I made my game on a mac, exported it for windows, then i tested it for windows 8 it opened, but the first scene after the main menu, was all black!! a black floor, all really weird and i wish i could do a screen shot, but all the images are to big. then i put it to a windows 7 computer, and it was fine!!!
