Can anyone help please? I've created a slideshow and used to be able to attach an MP3 sound file to play on a loop but now I get a "!" sign next to it and it won't play. Any suggestions?
Under the 'Playback' tab there's only the option for me to tick 'Audio' or not - I believe other people have an option for automatic or manual playback modes but I don't have that option.
