I installed UKMP 1.0 today without any trouble, and it works fine. It is an improvement over the built in media player, but I have 2 comments. 1: The cover art download wasn't always accurate, which I could correct manually. 2. UKMP had trouble with doubleCDs. It lumps them as one CD, and sometimes drops some of the songs. When it keeps them all, it doesn't maintain the correct order (all of CD 1, followed by CD 2). A lot of my music is Broadway musicals, ripped to mp3s by Windows Media Player. Thanks, Howard
