Hi Phil,
It worked for me yesterday but since it is over a month old, I thought it might have been taken down or something. Just tried it again, using Mozilla Firefox as my browser and it still works. It doesn't start immediately though, you have to wait maybe 20 seconds and then it will start.
I don't think it is using Flash player but just in case, check for a symbol that looks like a jigsaw piece on the address line, sometimes it is on the left sometimes on the right, depending on which browser you use (Firefox it is left, Edge I believe it is on the right). Click on it and if it says Flash is blocked, there is an option to 'Allow once'.
I hope that helps.
BAJ
