When you install winamp, try not to remove "the useless things" from it. I don't know but there might be something that let's the plugin play. Also make sure you have not ticked of the plugins that lets you play the audio codecs (like mp3, flac etc.). Also, what is your OS? This plugin only works (as far as I know) only on Vista, Windows 7 & 8.
