You can download Liquid Music and register a free trial, it will replace Liquid Rhythm but your original Liquid Rhythm license will remain in tact. 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 1.4.x or earlier Liquid Rhythm to revert back to your old license. You need not 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!
