"Try the wiki on playlists."
I have. Maybe you can point out where, in the wiki, it addresses disappearing playlists. I am not real bright so i could have easily missed it.
Read the wiki is the default answer to everything when a question is asked and rarely, in the few questions i have asked, does the wiki address it. Otherwise, when i reviewed the wiki, i would have found the answer.
Any other help you could provide?
