I am attempting to use the latest version of Free Audio CD Burner to burn .m4a audio files to audio CD. After the file names are entered into the "Conversion progress" window, every attempt to burn results in: "[Error: The file added to FileItem was not found! The file added to FileItem was not found!]". The various Customer Support Web links for the program's developer, DVDVideoSoft, show "page not found" (or similar) errors, and a Forum reply from a tech support person, from a year ago, says that this program (and several others) are no longer being developed or supported. What is the status?
