USELESS - Doesnt work after installing OsX Lion

I downloaded Magic Cutter from the App Store a few days prior upgrading the operating system to OSX Lion. Once Lion was installed the program does not work properly - It does not open the mp3 files and it doesnt work - Until the developer upgrades to an OSX Lion version this is absolutely USELESS. Besides that, it is a very simple wave form cutter.
