I recently re downloaded 2.5.5 for OS X. The Limewire icon came up the slice of lime; not the lime plug. Do I need an upgrade? If so, where do I get it?

The opposite is the case with me. I upgraded to Limewire Pro 2.5 expecting and hoping that the "plug"-icon would be replaced by the Lime slice. Didn't happen though. The plug just looks stupid in the dock. My question: how can you change it to the Lime slice?

I went to Pro Lime Wire and downloaded Mac OS X version 2.5.5 and it replaced my old set up. Viola...........a slice of lime. I like the plug in my dock, but no one is responding to tell me how.
