Mac OS X cannot be installed on this computer

Hi,

I was rushing though re-installation of Snow Leopard on my 2007-Nov Macbook. I accidentally hit 'Disagree' on the Software License Agreement screen! :@

I cant install Mac OS X on my Macbook now! Is there anyway I can go back to this and somehow agree! I never meant to click Disagree!

Appreciate any assistance with this!
