Derek, Tell us EXACTLY how you are transferring Larry's files to your SD Card. You can't just copy the Unzipped files directly to your SD Card - that won't work, because it does not update the very important 'INF' file on the SD Card. Unless the 'INF' file is correctly updated, the KN7000 will not 'see' the file.
An easy and foolproof method is to copy the unzipped file to a Floppy Disk, using your PC, feed the disk to your KN7000, load the file and then save it to SD Card.
If by chance you don't have a Floppy Disk Drive on your PC, then you can use Song Manager and do the transfer via USB to your KN7000 and then save to SD Card.
