installing

Hi there, I've just installed the theme as it's in the description, under the nailswithstyle.co.uk domain. I've followed the steps for the beginner users, as this is my first time with drupal. After install i can't access any of this: nailswithstyle.co.uk/admin, nailswitshtyle.co.uk/user. I have an idea that it could be related to modrewrite (htaccess problems?) Can you please help me pointing out where i've possibly made a mistake? I am using godaddy's hosting, and had an installation of drupal in the folder (clean basic one), but i've removed that completely before i've installed yours. regards, Tamas
