This application is now discontinued, because the official website doesn't exist. When you access it, a generic page is displayed instead. That page informs the user that AdvancedAnalytic domain (developers) expired. That's why you've encountered a website that "tries" to sell you something. That page displays domain selling offers.
Unfortunately, you won't have the possibility to download this software anytime soon.
I recommend using another application from the same category: http://software.informer.com/search/satellite+screensaver
