Smart DNS Proxy

[Oats]

Good Morning, can anyone help me. I am using Smart DNS to watch BBC and the like. For a week or so now I have still been able to watch catch up on these channels but not live. I have cleared the cache. Last night when I checked it was saying 'out of range'. I have not done anything different to normal, no updates etc so is anyone able to shed some light on this blip or suggest how I can get back live TV. Many thanks.
