Sorry to put this up because I know it has been asked in the past. Basically I did a trial of PowerDirector a few days ago and then bought a subscription. I have been using it fine and have produced at least 6 1 - 2 hour movies based on Zoom session recordings. However, I am typically not seeing the audio wave in the video clips. That doesn't bother me a lot most times. But occasionally I would like to see it and edit on the basis of what I see. My understanding, maybe wrong, is that this was an old problem that had been fixed. I am wrong? Any ideas?

After I wrote this and posted I saw that the issue is related to shadow files. While the program says it is creating them, nothing is appearing in the folder. One interesting thing was that just before this, when I was exploring the issue, I managed to crash the program. When I re-started it, it asked me about re-loading the project. I did, and the one clip I had in it came up with an audio wave and a shadow file. I then added other clips and nothing has happened to them - no audio and no shadow files.
