Thanks for your help. Can't quite get this to work.
Three quick follow ups: there are two items in the applauncher theme (a JPG and a KMP). Should both be named theme.swf or should they be included in a folder named theme.swf?
After I enter the command in putty on my pc I get this message (see below). Did it work? Or do I need to do something else?
Where does the theme show up? In the theme menu?
