I was using get_iplayer successfully up to yesterday (5th Feb 2018) using the latest 3.12. release and Windows 10, but today get this error:

The streamer message was also coming up in the previous version i was using (only downloaded 3.12 this morning).

Any ideas?

First example was using the pid identifyer, this also happens using the url method, except that it at least keeps trying!....
