Message says required update, MS "store" shows nothing

I’m not at all a fan of “stores”–playgrounds of the weak and feckless–but alas Microsoft thinks we are all as feckless as Apple users. So when my 120 dollar application told me this evening that I could not run it because of a “mandatory” update, imagine my chagrin when clicking on the “okay” button for that message (which should never, never, ever exist in the first place) led me to an MS store page for this product, with only a “play” option. No update, no guidance, no nothing.

So you have my 120 bucks Microsoft, and I have to go back to P3D to fly, and now I hate you much as I did in 2003 when I had to support NT and W2k servers and endpoints.
