Some of my MP3 files both pro and non pro format have mysteriously changed to layer 1 and Winamp 276 yes I know its old but has always worked without any issue and supports the Thompson mp3pro plugin. Now some of my files have changed to layer 1. I did not do anything tried using nero but it won't recognize layer one. I downloaded mp3gain and it informs me that the files are layer 1 not three. These are legitimate rips from CDs that I own. WTF is going on here? even the normal version nonpro are layer 1. my Moto g plus can't even play them... I have never seen this ever before. Help anyone?
