Server rentals :: NFOservers.com

It's in the correct place. When I created my account it gave me a website called like "username.site.nfoservers.com" but since I wanted to use my domain I deleted that one, are the files I'm uploading going to that one?

I transferred my domain from my old host earlier today successfully. Usually in order to install a forum or something of that nature I would go to incentivegaming.com/xenforo/install/install.php. I keep getting 404 Not Found and I am struggling to figure out why..
