I had both MP3 and WAV, neither one worked.
However, this message only affected on that 3-minute audio, I also have about 10+ sound effects (each last about 1 sec), and a 4-minute background music, these all plays fine, just the voice audio creates problem. The voice audio plays fine in other player though, and opens correctly in Adobe Audition CC. Also, this error message came out after I worked perfectly fine for about 5 hours.
