Sewing Machine Doesn't Work?

Someone dropped my Kenmore Ultra Stitch 12 sewing machine. It was working before this. Now the needle bar, the straight piece that controls the needle going up and down, doesn't move up and down at all.

The hand wheel, the wheel at the end that manually turns to make the needle go up and down, does spin. I opened it up and the larger, outer and the smaller belt also move, but the long horizontal shaft that connects the hand wheel to the needle bar does "not" rotate/move at all.

I've disengaged and re-engaged the hand wheel and made sure the bobbin winding assembly, the button on top that lets one disengage the needle to refill the bobbin, wasn't engaged. So it's not that. Just looking inside doesn't show me anything loose or bent. Any ideas? Please?
