Zune software: @!@#!@%#

Where are my playlists???!!! Gone! They are gone. Zune software just deleted all my playlists. I had everything organized and it is gone with the latest upgrade. No wonder people are afraid of computers. Wait a minute! They are back! Microsoft, don't scare me like that! Or are they back? I was scared for a minute. The playlists are back! Hurray! But wait a minute again! They are empty! My playlists are empty! No wonder people don't understand the computers. How can they trust them if the software they get behaves like that?
