After a year or two being dumb myself, I finally got past that activation key check. What I did was: 1: Temporarily connect to the net. 2: Type in random letters in the textbox. 3: Click the big 'A' activate button. And that's it. Turned my net back off and the game finally works fine. Hopefully that works for you too.
