Site is gone 404 Error

I created a site Pro-resultsfitness.com The server I am using is Network Solutions.

I created the site 3 weeks ago and now it is gone. At first Network Solutions said it was because I needed to point the URL to wordpress which I have now done and it is confirmed that it was updated. But wordpress isn’t recognizing my email or the other admin to the site as being associated with the site and when I type in Pro-resultsfitness/wordpress/wp-admin I get the 404 error and it says Hosted by Network Solutions at the end.

Also, I never received a confirmation email form wordpress with my IP address so I can’t even request wordpress to find it because I don’t have the IP address. But I do have emails from my website when I was testing different contact forms and adding my other admin member.

Help!
