I recently updated to v10.78 pro via the installer link I got from tech support, and when I opened a project I made a couple years ago, I think in the free version 9.33, I couldn't see the audio track. I can hear it, but not see it. The problem is the original project had an issue where the song used for the "soundtrack" wasn't fully repeated at some points, so it got cut off and started repeating at an odd place. I wanted to go back and fix that, but I can't, because I can't see the track to edit it.
I tried installing v9.33 again, but that didn't change anything. All I can see is the slides, no audio tracks like I used to be able to see. How do I fix this so I can edit the audio repeats and fades again?
