My old home PC died and I built a new one, but cannot reinstall Fences 4.  I get the "can't install because it is on another computer" error when I enter the product key.  When I go to store.stardock.com/myaccount/products/ and try to deactivate it from my old pc, I can't.  It only shows it activated on my work laptop.  I am supposed to be able to have one license and use it on one personal computer and one work computer, which is what I had with my old PC.  How can I get it onto my new PC?  Thanks!
