quick Harry Potter question - help help help!!!

ETA: Got it!

I'm in the middle of listening to Stephen Fry reading Chamber of Secrets and I have LOST disc #6!!!!

I remember at least one time when the cat knocked the set over and all the discs fell out, but I thought I had retrieved them all... apparently I missed one! It's probably around here somewhere... groan...

Is there anywhere I could download it? Does anyone have pirated backup copies of the audio discs posted somewhere?
