I did not install anything on my computer, I just went ahead and downloaded the 2 files directly on my N900, open terminal. dkpg -i both and voila, everything worked.

Maybe i'm from the few lucky ones, but I dont see the need to activate it through your PC.

Make sure you are conected to the internet on the phone when doing the verifecation and of course use the voice option, it worked for me.
