It a weird one. TalkTalk box (DN372T), go to nowtv app, entered the email address and password used to set up the nowtv account (I know these work as I can log on here) and it flashes up a capatia series of characters to prove I'm human. I enter these (correctly) and just get a 'sorry the characters do not match'. They definitely do. Tried turning the box off and back on again. Same.
