I am running OS 9.2.2 and have the newest version of Limewire 3.3.5 the basic free version. I downloaded a skin file, put the skin file on top of Stuff-it expander, the folder that it created I then put into the System Folder\Preferences\.limewire\themes along with the original file that it downloaded to my desktop, restarted and I now have a few skins to choose from. It worked great for me!
