I tried using The voice over but it isnt working. niether by importing nor by recording
Im Using the Free Version  so cant publish it either

There is something wrong with the MP3 file you have attached and I was also unable to hear it after adding it to a scribe. I have opened the MP3 file in Audacity (free audio recording and editing software) and then re-exported from there as an MP3. I've attached the file here and it plays in VideoScribe when attached as a voiceover to a scribe.
