How do I convert and transfer music from my computer to my dmg ds140 mp3
Did you transfer MP3 files, i.e files with a .mp3 extension after the name, e.g. StarSpangledBanner.mp3 ? From the error messages you are getting, it looks to me that the files you transferred are not MP3 files. For example, when you press Play, one or more files are highlighted and the player tries to play the first (or the only one) highlighted, but it can't because it is in a format that is not supported, i.e. not MP3. When you click Music, the player starts looking for all the MP3 files that you have on the player or on an external memory card. It cannot find any, hence the 'empty disv/card' error message.
