I also had the same problem. I've managed to get the cd player out (you must use 4 special wires that go into the four holes in the front of the player) and unscrew two screws (in each side of the player) to get the frontend from the player. Then I had access to the disk and pressing the eject i've got it out.
The problem is that, now, all cd's get stuck! Definitely something broke (a spring or something). It has to go to the repair shop.
