WindowBlinds 7 (7.4) activation

Hello friends,

Shortly i wanted to make a clean install of WB7 on my PC. So in order to do so i logged in and downloaded this 7.4 version from the Downloads section. After installing i wounder why the prompt for activation does not appear. I downloaded officially from the Downloads section - this means from my SD account.

Where can i get the WB7 enhanced? Why Stardock does not let me download enhanced? I bought a license some years ago.
