[orca-list] trying to install Ubuntu 14.04

[Glenn <glennervin cableone net>]

Hi,
Would anyone know why I cannot get past the installation window where it has 
two check boxes for "third party software" and "downloading updates"?
It is like the second window.
I can quit or go back, but forward is not an option.
I connected to my router first, so that is not the problem.
Even if I don't check these, I still cannot go forward.
Thanks for any help.
Glenn
