But, please clarify just where you are creating this slideshow. Are you really in the Elements Organizer 9 Slideshow Editor? I may be able to help you, but first - what are the properties of your audio that you want to add to the slideshow.....mp3, wav, other....is the audio really music from iTunes? You may end up having to convert the audio in iTunes before import into the slideshow project. But the answers will be in the details that you supply wherever you thread ends up.
We will be watching for your progress.
I'm using photoshop to create a slideshow to then import into premiere. I need the slides to fit the audio. But it is in the Elements Organizer. My audio is in an mp3 format. I have the song on my phone and transfered it onto my computer to use in the slideshow but got that error message. So then I used a SoundCloud converter to get the file, knowing iTunes wasn't an accepted format. I got the same error message that way. I have since ended up using a different song from my phone but if this is a simple fix, I would love to use the original one I wanted. However the party is today so I'm on a time crunch! Thank you for your response!
