Need Microsoft Frontpage Guru!?

I know a fair bit about web design and coding but i hired someone to make me a web site nd it is online now. but my contract with that company is over. but it seems that the company coded it so it always goes to the “under construction” page. I’ve called our domain name provider, and that is not expired until next year. my hosting company says our web hosting fees are up to date. So after about an hour of talking to different people at these places, I got a guy at MTS that knew what he was doing. He found out the issue. He tried changing a few things, but it did not work. He says he is not that familiar with front page. His recommendation was to get someone that is good with Frontpage to find out how to change that indexing so that it does not redirect the page. please help. thank you much!!
