Sorry, but the term "torrent download" is enough to lock this thread. Just buy the music you need in the iTunes shop and there will be no issues.
i used trader's little helper for years to decode audio files. i use it to turn something like flac into mp3 format so i can put it in itunes library. recently i've been getting this message. "at least one of the required subcomponents was not found. processing will be terminated."
not sure if it's a traders little helper problem or if there was a problem with my torrent download
