Error - "not a supported audio file"
I am trying to import audio into a presentation. I've used this audio numerous times, as it is our template. If I go out to the files and open them, the audio plays, no issue. When I Browse for the audio and try to insert it, I get the error below that it is not a supported audio file. I haven't moved the audio files, or changed them in anyway. I just imported them yesterday into a different presentation. Please advise. Thank you!
