If you were able to access your site a week or so ago, then this may be a little hickup due to the server transfers. I'd check http://status.x10hosting.com/ to see if your server is suffering any problems.
If not, then you may not have uploaded your site's files to public_html in your home folder.
Chopin is still in an account transfer state... You will have to wait a few more days, then everything will be back to normal.
