Have M2 for 5 years. 5/21/2016 video quits. When I login I see and hear the ads for John Hancock. When that ends I go to screen with all of the control icons, however the video is just black screen. I am using a macbook air with bootcamp and a dell that's about 6 months old. Tried both google chrome and Internet explorer. Turned off bitdefender firewall. Restarted, Deleted slingbox and then brought it back, with same result. I am on the road with no access to machine.
