I've tried to import mp3, wav, wma and it just hangs on processing. I've tried different types, different songs from different hard drives and even left it overnight to load. keeps on hanging. I've even tried to convert the mp3 audio file to mp4 video, which worked as a alternative, but lost the ability to edit sound volume and effects and then the video didnt want to export. I've restarted my computer 3 times and still nothing.
