Creo Elements Express 8.0 says no internet connection and wants a Proxy Name

[NH_10880054]

I just signed up for Creo Elements Express 8.0 and got the message that there is no internet connection even when my internet is working fine. The screen asks for a Proxy Name and Port, but I don't know what I should put in. I am able to bypass the screen and got a 72 hour countdown to use the software offline. 

Will I have to pay for the software after 72 hours? Why won't it connect to my internet through my computer?

Thank you,
