Can anyone help a new boy on the block. I normally convert all MP3's I download to AIFF files (I use ITunes as my default player) Until today everything was hunky-dory when, in the middle of converting my ITunes folder to Aiff Switch decided to only convert folders but not individual songs. I can't think what I have done wrong and on checking everything in Switch all appeared to be in order. Obviously some of my files are MP4/AAC as well as MP3. Any help will be gratefully received. Thanks.
