Site redirects from installation script?!

Hi there,

I’m a complete beginner so I could really use some help!
I decided to host my site at Dreamhost, and when they asked what domain name I’d like to register I asked for http://www.furtherado.com. All of this went smoothly until I tried to run the install script at http://www.furtherado.com/wp-admin/install.php – the site immediately redirects to http://www.furtherado.com.
Though this is the address I registered, this isn’t my site. I’m assuming this belongs to an old owner, and I’ve now bought it through Dreamhost. But could I have made a mistake here? Or do I have to wait a few days to be able to access and configure the site? I’ve followed all of the WordPress instructions – creating a database, renaming and changing the config file.

Any advice would be much appreciated!
