Search is your friend
Hi Cheech, remember, search is your friend!. Both I and Simon have had this problem:

I don't know about Simon but I have managed to fix mine.
In order, you have to remove...
1, the outer case
2, the dampers (they just push on to the pegs on the inner mechanism deck)
3, the alignment adjustment springs
4, the jack board
This will allow you to remove the mechanism deck from the outer housing.
Flip it on it's back and GENTLY persuade the stuck disk back into the magazine.
on the underside of the mechanism deck there is a lever which is part of the eject mechanism, push it and the magazine should slide out.
Now it back together by doing the reverse of the above points.
let me know if you need further advice...
