I only have setup and setup(1) and there is no link that gives me the rest :(
Like SinPrince said, this means you have downloaded more than one setup file, which you only need one. You need to delete your Version txt found in your game files (Right click your Last Moon icon and select "Open File Location" and there will be a txt file called Version.) Right click it and delete it. This will force an update (via the black automatic updater box that pops up when you first boot up Last Moon) and give you the necessary files.
