Hi, if your disk is still stuck then maybe this will help, I had same with a cd in car player and it worked for me, ok get a piece of fresh crisp paper, not too thick but doesn't want to be too tissue like, so try to push the paper into the slot where the disk go's in, the paper wants to be about two thirds the width of the disk, try first to get the paper on top of the disk and try ejecting it then if it fails try getting the paper underneath, often if they get stuck its because of labels coming off copy disks and sometimes you find the edges of the disk get slightly damaged and are just catching, got to be worth a try as its free to give it a go.
