Domain forwarding not working properly

Okay, so I’m attempting to set up a website on Byethost using WordPress. The site’s URL is http://seraphiscain.byethost14.com, and I’m using the domain http://superiorattack.tk as a forwarding URL. The problem is, with the way it’s set up now, clicking on a post’s title or trying to use a permalink sends you right back to the main site page instead of taking you to the post’s page. In an attempt to fix this, I tried installing WordPress to the superiorattack.tk folder on the server, but when I try to access http://superiorattack.tk/wp-admin/install.php, I once again get redirected to the main blog page.

For example, from my main page, if you click on the post “Super Smash Bros. rated by ESRB”, it SHOULD theoretically take you to http://superiorattack.tk/2009/12/super-smash-bros-rated-by-esrb/, but instead it just redirects to the main blog page.

Any idea on what I’m doing wrong here?
