Looking for a little help here. I've been using my slingbox M1/M2 for about 8 months now with no issues. Now, out of nowhere, I'm able to launch the slingplayer, but nothing shows up on the screen. I've tried with my android phones, windows laptop, iPad, etc. and all devices are having the same issue. Any help would be greatly appreciated. There has been no change in the cable box, TV, etc.
