Wow, you must feel like a complete idiot for waiting that long. They don't sell a CD. No where does it say that they'll send you a CD. Go to here:
http://www.limewire.com/index.jsp/supportpro and enter in your e-mail address. It will take you to a site where you can DOWNLOAD LimeWire Pro.

PS. I admit that the picture of the LimeWire box is somewhat decieving, but only if you don't READ anything at all.
