Thought I posted this this morning, but can't find it anywhere. Apologies if duplicate.
MP3 files are not playing in SVP16 (trial version) on time line. Also, clicking on them in project media does not make them show up in the trimmer, even though that feature is checked in preferences. Right clicking on an MP3 file does not allow "open in trimmer." That option is grayed out. All of the above do work with WAV files, however.
