Can't View Website

I have just gotten At&t internet and have learned I can't view a site. It is imported to my livelihood. that I can view this site.

The site is 4ove.com  I have used other internet serves and had no problem on my laptop. I can't even get to it by using my Ipod. I can view the hosted site, but can't get on the main site to edit my own site. Any ideas as to what to do or why it isn't working?
