Is there something that I am doing wrong trying to convert large m4a files to wma? I don't care about the loss of sound quality because I am converting audio books and only using voice quality settings. I used iTunes to convert the cd to m4a files and used the "Join CD tracks" to combine all the tracks on a CD into one file. Files come out about 35,000 KB. I get the error message "The creation of output file failed." I'm using Switch V 1.12. Thanks for the help.
