Sorry for the delay, I've been away.
Looking at the settings today, it didn't have any devices registered.
I therefore tried watching Virgin Media on my laptop, it told me to register it, which I then did, but still won't play the tv channels.
It just says, once again, register the device, but it already is?!
Looking at the list of devices, it has added my laptop as a device, but still keeps coming up with a message saying it's not registered when trying to watch tv
Looking at the registered devices on the Sky channels, that is showing 6 devices?!
