Are you saying sky have released software that for it to work needs you to disable AV protection? Behave yourselves!
I managed to get away from the black screen, I had to add manual firewall rules for both sky go and the Cisco junk (seems the installer doesn’t do this), it still takes ages to load to the screen though, then the next issue. Can’t actually see the login box details so managed to wing it (shows a white box) somehow logged in through pure chance, clicked on the sport, it tried, crashed and shutdown. Spend 2 hours faffing with the app, whilst trying to watch the game, saw it mostly on my phone screen.... why can you get it to work on millions of phones and tablets but not on a PC?
Massive failing.
