I'm having problems accessing bbc radio iplayer whether I'm trying to stream or access a stored broadcast. All I get in the pop-out window is the 'Sound of Silence' page which talks to me about a mis-match between the service and my device, and when I try to play a stored programme through the main window, it doesn't load. I haven't changed the ISP (Orange) or my device (laptop running on Windows 7) or any permissions since March, up to which point it was working fine, apart from very occasional buffering issues. We live in suburbia with a relatively good speed (but no fibre).
I have disabled TrackMeNot, Ad Block Plus, Ghostery and NoScript on bbc.co.uk (all added by my security-mad brother), run a complete virus scan with Avast (nothing came up), updated all the common software like Java, checked the permissions for pop-ups in Firefox (which updated itself last week, but the problems with iplayer radio pre-date the Firefox update), and emptied the trash bin (and re-started), all to no avail.
Can anyone suggest something else I could try? It's my only connection to the UK as we don't have cable or satellite TV, and I often use it for personal and teaching use, so I'm feeling very frustrated and abandoned! Thank you in advance. . .
