Problem with Dreamhost automated installation

Hi, I followed the instructions with my web host, Dreamhost, for automatic setup of WordPress on my website (primp.ca). I got an email confirming the set up was complete.

The first line of the email says:

1. Please create an admin user at:

http://www.primp.ca/wp-admin/install.php

However when I click on this link I just get a page from Domains at Cost, the company I purchased the domain name from.

Can someone tell me what I am supposed to do now to get my WordPress running?

Thanks,
Michka
