Lots of hours of downloaded programmes on my IPad via BBC Iplayer have disappeared. I downloaded a bunch of programmes in readiness for a trip and now I am away they have all disappeared. Except I know they are on my IPad because of the space they take up. And they haven't expired, they all had *30 days to run when I left the UK last week. My only option seems to be to reinstall the app but then I lose all the data. And the BBC doesnt reply to my request for help either. Any ideas?
