Necchi Sewing Machine. Bobbin/Spinning wheel on the side of the machine does not work. I needed to

Question

Bobbin/Spinning wheel on the side of the machine does not work. I needed to fill my bobbin so I tried 'unsticking' the inside wheel. It was stuck pretty good, then finally I got it. Ok, so I filled my bobbin but now it will not get back to where it was. The needle will not move when I push the pedle, but the wheel spins. What can I do to fix it?
