I had a strange thing happen with the beta. I had over an hour of live audio recorded in a file, but was disappointed later when I could not find it.
I was able to replay it immediately, but after shutting down OneNote and then the machine, later, I could open OneNote, see the same page (I had made some notes about things), but there appeared to be no audio.
Over the last month I have opened the OneNote beta to see if I could find and play that audio segment. No joy.
Installed the release version of OneNote last night.
The installation routine "noticed" the beta and asked for permission to remove it. Fine.
Then it "noticed" that I had some data files that needed to be updated. Fine, I've already lost what I cared about the most. Go ahead I thought.
When I opened OneNote, the audio was there!
