My Sansa Clipp+ mp3 player, when connected to the computer, doesn't show the music files anymore.

In the good ol' days I could actually manage my music and recordings from my PC.
Then something happened, but I could at least see shortcuts that would open the relevant folders.
Now I don't even see shortcuts anymore, everything treated as hidden system files, so I have to change the view settings in Windows Explorer in order to see them.

A workaround is to save a shortcut to the relevant folder on my PC, but is there any real solution to the problem?
