I'm so glad to hear that re-registering your device after the Windows 10 upgrade on your laptop worked
I have to admit, I was one of those people attempting to alleviate the holiday boredom on New Year's Day, but eventually gave up trying to get online and had to resort to watching my Game of Thrones box set the old fashioned way--via DVD on the TV...Winter's coming, by the way—as you said, looks like we’re in for a cold and soggy one!
Apologies that you were experiencing problems accessing TV Anywhere in the first place after your upgrade.
As long as you are connecting your device via WiFi (not 3G or 4G), then you should be able to access your TVA anywhere within the UK--you don't have to be in your own home.
Please let me know if I can help further.
