I have had my Slingbox 350 for several years now and it has worked great. For some reason it stopped. I reconfigured it but nothing. If I try to use the desktop app it shows a blank screen. It shows that I am connected to my 350 and I can sit at my computer and change channels with the remote on my TV but no picture on my laptop. My cable service scrolls their logo across the screen when you first turn on the TV until you select a channel. I am getting this scrolling logo and can't get it to go away. Changing channels does nothing but change the TV. Any ideas about what has changed here in my set up?
