Hi,
I'm running a Windows 10 64bit. I had the Photostory 2022 and was trying to create a slideshow. I have added the pictures (JPG & JPEG files) and music (m4a) and some snippet videos (mp4 & MOV). When I try to preview the slideshow, it plays normally for about 2-3 seconds and then it stops, and I get this pop-up screen showing the error "Cannot prepare WAV header". I uninstalled and reinstalled it, started a whole new slideshow and again the same error come up. I completely uninstalled Photostory 2022 and purchased the Photostory 2023 ($39 not the upgrade) and the same error appears.
