As Mark & shredd said, this is probably all in the stickies... but fwiw, here are some thoughts on various culprits for 'protected' songs, assuming it's not the usual 'running out-of-date firmware'.
The card itself can be protected by sliding the small switch on the card body. This can be done inadvertently when plugging the card in by catching the side of the card against the holder. This is unlikely to be your problem as it would stop
any writes to the card, including writing to the AudioDepot from your computer... although if you removed the card to do this, you may have caught the slide switch when moving it back.
Another culprit is the machine's own 'protect' setting, which is indicated in the song list by a padlock next to the song name. The song menu setting toggles this on and off. This will prevent any updates to that song, but it won't affect AudioDepot as the latter is a global folder accessible by all songs.
The last one I can think of is the standard 'read only' attribute which can be set/reset using a computer. If your computer has set this attribute on any of the files within the song folder, or even the song folder itself, the machine will be unable to write to them and may give that 'protected' message. Maybe you tried making an archived song read-only for safety and forgot to change it back?
To check the latter, put the card into your computer, or use the USB link, and check the properties of the song folder and files within it. There are several ways of checking depending on your computer, e.g. one way might be to right-click the item and select 'properties' or file attributes.
Hope you find the cause... let us know if you do.
P.S. welcome to the forum
