First I record audio with PD14's Voice-Over Recording Room. That of course lays down a track of what I said. It plays fine and sounds fine in PD14. If I select the track and then select Edit Audio/WaveEditor or Edit Audio/AudioDirector then I get an error in the other application. It worked before I switched to Windows 10, but now in WaveEditor it just says "Files not imported" and in AudioDirector 6 it says "An error ocurred while opening this file in the media library. It may be because the file is broken or is in an unsupported format. Try contacting your audio provider for a different audio format." The file format is of course WAV because that has always been what PD13 and PD14 have created when I capture audio in the PD editor.
How can I get these WAVs fixed and loadable in WaveEditor and/or AudioDirector? The only help I found was to "update QuickTime" which I have alredy tried.
