Activating Dragon Age: Origins without internet connection?

Is there a way to do this without being connected to the internet? I lost my internet on saturday and until we can afford it again I can't  connect to the internet at home. Is there a way to activate it without having internet, or am I screwed until I can get some form of brief internet to activate it? I'm stuck with only the library for internet and it's a desktop so I can't just take it with me to use library internet.
