I have an m4a file (it originally had the extension m3u, but i saved it in a way to where the extention is now m4a), and tried to use my dbpowerAMP Music Converter to convert it to mp3. When I got to the point where it asked me to enter the file, when I did, a box saying "Support for the audio type '.m4a' might be obtained at 'Codec Central', vist codec central now?" with Yes/No box choices. I clicked "yes," went to codec central and downloaded all the ones that seemed to support m4a files. But when I try to use the dbpowerAMP Music Converter again to convert the file, I still get the same message that I got above. I'm not sure what I'm doing wrong. I'm very new to this stuff (and just computer stupid), so please be gentle with me!
