Internet Radio suddenly missing and replaced with BBC iPlayer which does not work

I'm not sure whether there has been an automatic update to cause this, but when I last looked for Internet Radio, there is nothing listed anymore. Just the BBC iPlayer icon and when I click on this nothing happens.

Perhaps I installed something but I really don't recall.

Anyone else seen this or know of a cure? I've done the old turn it off and on again a few times.

Thanks
Dave
