Activate Hathor Site goes Blank

When I go to activate the theme Hathor, my whole site goes blank (or won’t load). Even trying to get to the site through wordpress it’s blank. I can’t even load the dashboard. I have downloaded the zip file 3xs activated 3xs and have had to go to my HostGator to delete to get back to my dashboard. Thank you for your help on this.
