For some reason, my Slingplayer no longer works properly - I can connect ok, but the buttons don't work (nothing happens when I hit ok to select or try to pull up the program guide or recordings). This problem seemed to coincide with with a recent upgrade to the App. I've tried uninstalling and reinstalling the App. Also - i've turned on/off the Slingbox. Finally - I saw a suggestion to hit back a bunch of times and relaunch the App - that also didn't work. Any suggestions? Thus is really annoying - as it worked perfectly before.
Have you installed a new Set-Top-Box recently? If so, you may need to reconfigure the Slingbox for the new Video Source. please check out this article for instructions on how to add a new video source:
