When I try to see my webpage using the URL http://Lourdes_52.drivehq.com , a blue screen with the title "How to Publish Websites on DriveHQ.com"   I sign up with a Trustable e-mail.

This is correct.

Please read the content of the sample page about how to publish your website. You must upload your own HTML files; otherwise, you will see the default web page - which is correct.

Now if your web page file is index.html, please make a copy and overwrite the default home.htm file.

Files put in the wwwhome folder are accessible with this URL:

http://USERNAME.drivehq.com/FILENAME
