no iPlayer files created on & after Monday 7th can be downloaded - either they finish but with zero byte size or never complete (and have never downloaded any bytes). Files created before are OK.

Case Closed.

I installed the downloader on a separate machine which does not have a VPN unblocker installed & it works fine
