Since your Desktop stays stuck on "Launching Slingplayer" what I recommend for you to do is go into your computer and un-install and re-install the Slingplayer plug-in, as well as the Slingplayer for desktop. You can download the Slingplayer for desktop by going into Slingbox.com >Products>Slingplayer apps. Before you re-install the app or the plug-in, I recommend you to delete cookies and cache from your browser. Keep in mind this could also be firewall issue. Below is helpful link:
