I am having the exact same issues as the above poster
This has been an ongoing issue since upgrading to Windows 10.
Sky go worked perfectly on Windows 7.
Upgraded and ever since Sky Go will not work on I.E. or firefox.
This includes watching it live and watching any on video on demand.
The error on live is a black screen that will not load, even with an unregistered device slot available. Interestingly the video will work on the 'free' channels.
The error for on demand is that the 'watch button' will show up and when clicked will not respond in anyway.
Fixes attempted:
Silverlight has been reinstalled several times
Internet browsers updated and reinstalled several times
Language fix that is on other forum posts.
So far none of these has worked. Does anybody have any other fixes for this?
