Someone please help, ever since the NOW TV app was required I have not been able to watch on my MacBook Air, at first it was just a black screen with no sound and now this error code.
It's ridiclous, NOW TV are refusing to give me a refund even though I have not been able to watch anything for a full month, horrible service.
I've just had error p1301 too, on my Mac, having just installed NowTV Player.
Are you using a VPN?. I couldnt connect (even when setting the VPN to a UK venue).
Dropping the VPN allowed me to connect (even when, once connected to NowTV, I then reconnected the VPN)
