Which version of Flash Player have you installed, you need the debugger version. Check your browser , some browsers like Chrome for instance , come with Flash Player bundled in , but this isn't the version you need. You can also check your application properties, particularly the Run/Debug Settings. Last but not least, you could also watch this Lee Brimelow tutorial, about using MonsterDebugger http://gotoandlearn.com/play.php?id=109
