I'm trying to watch live tv on my laptop which is registered as one of my 2 devices but when I try to select a channel it says "this device is not one of your registered devices". It also says I can't change a device until 1st March so can't delete then re-register until then (which seems a ridicules rule by the way).
Sorry to read that you're unable to watch TV Anywhere on your laptop.
I would like to get this issue resolved for you, however I was unable to locate your account. I've sent you a PM (purple envelope icon, right corner) with some details for you to confirm please. Once you have replied I can look into this for you.
