login issues – upgrade from 1.02 to 1.2

I have successfully upgraded from 1.02 to 1.2. I now have two seperate folders. However, when I try to login to wp-admin in the upgrade which is https://www.woolever.com/wordpress/wp-login.php it redirects me to https://www.woolever.com/wordpress1.02/wp-login.php. If I delete the original 1.02 folder then I get a broken link when I try to login. I am sure it is just a change of reference somewhere in the settings but I am not sure where. Any help would be appreciated.
