Running Presenter '09 on a Lenovo T420s with Windows 7. I've written a lesson and was editing it. I tried to open Audio Editor -- it started to open, then I got an error message. Closed the PPT file, opened it again, and opened the Audio Editor -- there were no "sound waves" visible. No audio, either, when I tried to play. If I open "Record Audio," each slide lists a length of 0.000.
This is the second time this has happened, but the first time it was only on select slides, so I just re-recorded the audio. But this is an entire 17-minute lesson.
FWIW, this never happened on my old Dell laptop.
The only other thing that happened is that there is a Notepad file titled "ae" that suddenly appeared in the same folder, created right about the time of the first error message. The entire contents of it are: [Presenter]
Your help is appreciated, I need to deliver this lesson tomorrow.
