cd magazine stuck

The magazine is stuck in my cd player under the drivers seat and if I press cd on the player it just says "no magazine". I have got it out in similar circumstances before by fiddling and banging but its not working this time. Has anyone any tips on a) how to release it and b) how to fix the problem? All advice appreciated!

With a Philips CD multiplayer placing a credit card or similar over the to of the cartridge trips a micro switch and the cartridge pops out.

Ace! I'll give it a go tomorrow!!

Sadly not worked! I had a right good poke about too.

I had to press the eject button loads of times but my magazine came out eventually.
