Login directing to wrong site

Hi –

New to wordpress. Here is my problem. I currently have a site up using a different set of blogging software. I am in the midst of redoing the site on a new server using wordpress. I would like to install wordpress on the new server and then work on the page using a preview site that my server offers – leaving my current site intact.

I was able to install wordpress just fine on the new server, however, when I go to login it attmepts to read files from my current (old) site rather than the preview (new) site. How do I fix it so that it won’t attmept to look for files in the old site? I would really like to set up the web site without it going public so any help would be great. Also, I use Laughing Squid as my server – if that helps.
