After installing 1.4 and when i went to play at the club. the songs that i imported before installing 1.4 got deleted from my external firewire drive. To my amazement my crates had missing files or "files not found" for the last 3 months of promo music that i loaded. Just a minor problem and irratant more than anything but definitely a problem at the show because the music the client was requesting was no long on hand.
