How can I eject a jammed CD from my X Type (2003) Jaguar?

I can hear the mechanism working,and the word 'loading' is displayed intermittently ( see below )but the CD does'nt play,and when the Eject button is pressed,the CD stays put.I've tried to move it gently by inserting a narrow blade but without success and these 'movements' activate the 'loading' message,which disappears and is replaced by the permanent message ''CD Error''
