I got a pop-up stating:
Please install Flash Player HD to continue (required)
There is more information. The flash player symbol looks a lot like yours, but it is not exact. I knew it would take me to a web site first, so I clicked on it.
It took me to http://www.playerinstaller.com/Install/
It looks suspicious. I wanted to be sure whether this web site belongs to Adobe or not - or is a legitimate site offering your flash player - before I download and install.

You are correct to be suspicious; "Flash Player HD" is not an Adobe product, and the website you linked does not belong to Adobe.
P.S. this is a public forum; please do not post your email address.
Thank you very much, Pat!
