Need the adventurous pro 1.2 files

Hello, i was trying to make some changes to some php files, then something went wrong and now the entire site went down, i cant even login to wp-admin, i tried reverting the changes from my cPanel file manager but apparently im missing something because it just wont work, the files in the Adventurous Pro 3.0 seem a little bit different from the old ones my site was using so using those files could make it worse... if that is possible, i urgently need the adventurous pro 1.2 files, i was working in the adventurous-custom-header.php file, hope you guys can help me soon because the site is down and it is very important for this company to work, thanks! The site is: www.elbedroom.mx
