Fatal error message – blog totally disappeared

Hi, I updated my blog (partial) at https://www.spainstruck.com and now it′s unreachable. I get this message:

Warning: require(/home1/albamodo/public_html/wp-content/themes/genesis/inc/customizer.php) [function.require]: failed to open stream: No such file or directory in /home1/albamodo/public_html/wp-content/themes/prose/functions.php on line 196

Fatal error: require() [function.require]: Failed opening required ‘/home1/albamodo/public_html/wp-content/themes/genesis/inc/customizer.php’ (include_path=’.:/usr/lib/php:/usr/local/lib/php’) in /home1/albamodo/public_html/wp-content/themes/prose/functions.php on line 196

What should I do? Thank you.
