Issue with firmware upgrade - playlists lose info

I just installed the V01.02.26A firmware upgrade on my Fuze.  Now, in the middle of playing music, the length of the music files goes to 00:00 seconds,the player rapidly scrolls through the playlist and nothing plays.  I have to reboot it to get it back to where it plays normally.  Has anyone else seen this and how do you resolve it?  I’m considering rolling back the firmware to 1.01.
