2000 BMW 323i cd player

hi
i`ve got my 323i almost 2 weeks ago,so far its just awesome,but last night when i`ve put mp3 cd into my factory bmw cd player,it got stuck.....the player wouldnt just give it back no metter how many times i pressed eject button,also when i was pressing "cd" button it was saying "cd error" but still wouldnt give it back.....i got pissed and was going to take it out the other day.....but it just elected it
