I'm trying to add audio to a slide show. I've done it before on this computer with no problem, but now it's telling me I don't have the correct compression files installed on my computer. Not sure what to do next.
What is the exact error message? Can you share a screenshot?
Does the error happen right after choosing slideshow option or does it happen when you try to save/output it?
Which version of PSE and OS you have?
