Did you change your nameservers to Avangard Hosting?
You will need to do this and allow the 72 hours for propagation before being able to publish using FrontPage. You are unable to publish using FrontPage until your domain is pointed towards our servers unless you make an entry in your local hostfile. server ip http://www.domain.com
We suggest using an ftp program to upload to your site until the domain name propagates.
