application not found when opening cdrom

When I insert a CD, it will bring up WMP. If I double click on the CD rom drive or right click it and go to play it gives me the error "application not found". I have made sure that AutoPlay settings are enabled in the control panel. I finally figured it out! I went into the registry with regedit. I browsed Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Classes\AudioCD\shell\play\command and changed the default key back to C:\Program Files\Windows Media Player\wmplayer.exe /prefetch:3 /device:AudioCD "%L" and all is well again. Rhapsody had changed my registry, lovely.
