Dunno if this helps, but if you manage to get a Lv. 3 special in the Hard mode final boss, you can usually Dair-spam (D in mid-air) your way to victory, provided you get the timing right.
@Chainsaw24: Once loading hits 100%, just right-click, select Play, and you're good to go. Although it would be nice to play the game w/o having to do so.
