I'm retarded - putting in password

So when I click the ‘online’ button from the main menu, it pops up a window asking for the registration code. I bought GSB and the Tribe Expansion pack online, but where did I get the code? I got a couple emails which had a ‘product ID’ # and a ‘password’ #, but none of those seem to work. Am I missing something somewhere? I want to do some online challenges.

the code is in the same email as the downlaod link (if you bought from positech) and it looks something like this: (dont type yours here!)

1111-1111-1111-1

god I’m an idiot. There it is, clear as day in the email. Thanks! Right, now to blow some other people’s fleets up…
