Radioplayer will not work

what operating system is this on?

What does 'will not work' mean?  Is there an error message?  If so, please provide a screenshot (https://forums.adobe.com/docs/DOC-7043#jive_content_id_How_do_I_attach_a_screenshot )

What is the exact url/link to the page in question?

<edit>

On a Windows 7 system with the latest version of Firefox, I navigated to http://www.radioplayer.co.uk/.  After accessing several non-Flash stations (http://www.heart.co.uk/80s/radio/player/​,  http://www.bbc.co.uk/radio/player/bbc_1xtra​, http://ukrp.planetradio.co.uk/?station=planet-rock), I finally encountered one that prompted me to install Flash (https://www.planetrock.com/radioplayer/​).

I clicked the 'update flash' link and was redirected to get.adobe.com/flashplayer.  I downloaded and installed Flash (no error), confirmed (at helpx.adobe.com/flash-player.html) that it was installed.  I then went back to https://www.planetrock.com/radioplayer/​ and enabled Flash on this site (see Why do I have to click to activate plugins? | Firefox Help ) but the audio still wouldn't play - just remained at 'loading....' and then after a minute or so prompted to install Flash again.  This suggests an issue with the site, not Flash.  Please contact the content developer for assistance.
