I have the 14 day entrainment and I was watching the game of thrones from season 1 and now it has disappeared and I can only watch season 6 and I haven't watched all the others. If I pay the month payment will they come back so I can watch all of them?
The answer to your question is sadly no. Seasons 1-5 have now left the NOW TV service. And the 'catch-up' episodes from the lastest series (season 6) expire 30 days after their original transmission date!
All of which was stated within the original GoT blog, way back on 04 March 2016!
