Is it possible that by editing a presentation, then saving it under a new file name, (ex:...rev 2), that it would cause a disconnect of the link between the .wav files and the presentation?

I have the original presentation (and the revised one), and the .wav files in an isolated stand alone folder.

The slides have the speaker icon in the lower right corner, but there is no sound when I play the Slide Show.

Thanks for any feedback.
