I was trying to sync some playlists to my CZ.
On trying to play these lists, they were displayed as empty, most likely because MM has specified the files' locations as N:\Music\...,
"N:" being the hard drive letter the device accidentally had on my computer, "Music" being the folder all music on my CZ goes to.
I had manually replaced "N:\" by "..\" in notepad so now they work.
But this is not the way syncing music should work in 2012???
