Spray a bit of WD40 into the bit collet, let it sit for a good hour.

This series uses a ball detent to hold the bit. When you slide the knurled ring down the ball should loose its tension allowing the bit to come out. Rust or debris can jam the ball detent. You could have used the wrong bit too. Once you can pull the ring down grab the bit with some pliers to help pull it out.
