Renamed .htaccess and now my main site is down!

Hello,
We are WP 2.7.1 users using lunarpages web hosting. We have been working in a sub domain, testing on a non live database. We were having problems with the theme Arthemia Premium, and the author had us delete the .htaccess folder in the subdomain folder, and now our live site, http://thefullpint.com is not working.

Please help, as our site is completely down.

Thanks,
Dan
