Can't connect to steam to register my copy

[Kent]

I bought Emergence yesterday, but I found out that the internet connection at my campus dorm is fire-walled and won't allow me to connect to Steam. This means that I can't register my copy of the game which in turn means that I can't start playing it.

Is there any way to register the game without going through Steam? A phone number that I could call, perhaps?

Thanks.
