Cubase LE5 download access code

Hi, I’m in Malaysia. I’ve just installed and registered the Cubase LE5 software which came together with the TASCAM US-600. There’s no 25 digit download access code to be found in either of the manuals. Is there any place I can get it? I got the Tascam unit from a friend as part payment for some guitar repairs I did for him so i don’t know whether there’s a missing piece of paper with the code on it. It seems to be a bit difficult to email Steinberg directly, any help will be much appreciated, thanks.
