I had a 71 MB ppta. Recorded a little more through Record Narration. The ppta file then became 10 MB. All my previous narration was gone; I had only the audio for that latest session, as if the ppta got replaced, not updated.
I am using Presenter '09, V6.3 on a local "C" drive. Have not changed the file name. Have not moved locations.
I had backup all files so I can restore it, but I need to know:
Why is this happening and how can I prevent it?
