Lost all images in Keynotes for your college lectures

Hello,

I spent a great amount of time developing 15 keynotes for an art history course. I've upgraded to a new macbook (early 2013 retina) and bought the Keynote 09 5.3 .

Now I've lost all images on my slides? This is infuriating! I copied the folder of presentations to an external drive. They also do not show up when accessed from the old macbook using the drive. Nothing is corrupted on the external drive but these keynotes.

I see images on the thumbnails. But the slides show placeholders.

Please help!
