Can't add Audio to Library in Animate

I've tried both mp3 and WAV, both fail. I've ran my files through Media Encoder and switched them to 44.1kHz 64kbps and they still fail. Oddly there are some files that do work for whatever reason (and they happen to be mp3 files). The only pattern I've noticed is that ANY audio file I had in my computer before installing Animate works fine but EVERYTHING I've downloaded since fails no matter what. 

I'm attaching 2 files, the first is a file I had in my computer before installing Animate, the second one is an mp3 file I ran through Media Encoder to change it to WAV. The first file I can import fine but the second one (in both the original mp3 and WAV) cannot be imported.
