Importing audio to slideshow

Having problems imorting audio file to slide show. I always get an error. This is an audio file I downloaded from Walmart. Maybe it is some kind of licsense problem. I am using Nero 7. Not a problem with other audio files I have on my computer. Any help would be appreciated.

I am having the same problem. I can use a “sample” clip (wma) format of Beethoven that existed in the My Music folder, but when I try to download a wma file from walmart & insert, I get an error message. This same message comes up no matter what format I try to add to the slide show. I hope you get a reply that can help us both
