I just acquired an old Slingbox. It is either a Sling Box 100 or Slingbox HD. Either way, I can not get started trying to see if I can access it because I get error message when I go to the "other Slingbox"setting indicating that the browser ior operating system s not compatible. I looked on the chart and my browser and operating system should work. I have 3 different computers with windows 10, 7 and XP yet i get the same message , Any help?
