An error of code in functions.php which means I can’t install my blog! HELP!

I uploaded everything to my website and then went to http://thebestclubpenguincheats.com/wp-admin/install.php as told in the readme.html file. It showed me this message:

Warning: require_once(/home/a1434532/public_html/wp-includes/wp-db.php) [function.require-once]: failed to open stream: No such file or directory in /home/a1434532/public_html/wp-includes/functions.php on line 2772

I assume that a line of code in functions.php is not correct. Until I fix that I cannot use my blog. How do I fix this?

Please reply as soon as possible because this is really urgent!!
