You need version 1.3.610 or later for it to work. Also I am on Win7, so I know it works on that, but I don't know about Win XP or OSX. I contacted Enrique at support and he sent me the new instructions that were available. They are still in beta (I think). The new skinning commands are not yet fully published and only work on Nebula after version 1.3.610. I recommend contacting help desk to get the info you need. Hope this helps.
