lost keey

I cant find my activation key and have since changed email address and no longer have access to old account so I cant use recovery tool 
does anyone know what I do now

If you click on the "order Beersmith 2.2" link above.
Then click on "support"
scroll past the part that tries to get you to post here on the forum
click on Contact Us.

That is what I would do. Not sure if you'll have any luck or not.
