Can not access Wordpress dashboard or blog

I need some serious help. I someone unhosted my website and blog from dreamhost. I got my website back but my blog is still not available. When I put in the web address for my wordpress/prophoto dashboard I get this error: The requested URL /wp-login.php was not found on this server.

Additionally, a 404 Not Found error was encountered while trying to use an ErrorDocument to handle the request

and the web address is now showing

Can anyone help me get my blog and dashboard back??
