Hello, I can't import an MP3 file even if this format should be a recognized format (http://help-nv10mac.qsrinternational.com/desktop/procedures/import_audio_or_video.htm). As stated on this link I tried to open it in Quicktime and exported it. As you can see from the attached screenshot, also this solution did not work for me.
Did anyone have the same problem and found a solution?
