The license may be tied to the identification of your network connection:
Did you request the license for the wired (LAN) connection and are you now connected wirelessly (WiFi)?
Or vice versa?
Success!

Can you describe how you solved the problem, or did it just ' happen tot work' after enough trying?Luc
