You can download Liquid Music and register a free trial, it will replace Liquid Rhythm but your original Liquid Rhythm license will remain intact. You can register a trial for Liquid Music and you will also have a trial of Liquid Rhythm at the same time. At any time you can uninstall Liquid Music and re-install Liquid Rhythm 1.4.x (or earlier) to revert back to your old license. You do not need to re-register Liquid Rhythm after doing so. We hope you love Liquid Music as much as our Liquid Rhythm users do and you will buy Liquid Music!
