Access Denied

I have a new installation hosted on GoDaddy. The installation went well, and I was able to access the site, make changes, etc.

I have FTP access and have the option of replacing any files or starting over. The site address is: 

Thanks for your help. I have been a user on an elgg site for years and have some limited experience with HTML.
