301 moved permanently problem can't access site

Hi,
I recently got my cPanel account with my new host. I used fantastico to install wordpress. I had to delete and reinstall it several times due to a few mistakes I made in the configuration. One was that my website showed up as http://slam-man.com instead of http://www.slam-man.com so I changed the URL settings in wordpress. Now when I access http://slam-man.com it gives this error:

Moved Permanently

The document has moved here.

Additionally, a 500 Internal Server Error error was encountered while trying to use an ErrorDocument to handle the request.
Apache/2.2.8 (Unix) mod_ssl/2.2.8 OpenSSL/0.9.8b mod_auth_passthrough/2.1 mod_bwlimited/1.4 FrontPage/5.0.2.2635 Server at slam-man.com Port 80

This still happens when I delete the wordpress installation.

What confuses me is that it says the "document has moved here" link points to exactly the same URL!

Typing http://www.slam-man.com gives this

Index of /

* cgi-bin/

Apache/2.2.8 (Unix) mod_ssl/2.2.8 OpenSSL/0.9.8b mod_auth_passthrough/2.1 mod_bwlimited/1.4 FrontPage/5.0.2.2635 Server at www.slam-man.com Port 80

I've done a search on the web about this but I couldn't find anything.
Appreciate the help!
