How do I fix an error loading page could not resolve hostname

When I try to run unity and it reaches the license page, a tab appears and says error loading page could not resolve hostname. When I exit out of the tab, unity closes. When I try to ignore it, nothing seems to work. Can anyone help me?

All you got to do is simply get back the Manual Activation Window by going offline.

I just published an extremely simple guide that anyone can use on my blog - [Solved] Unity 3D License: Couldn't Resolve Host Name Error! - Digital Conqueror
