My Upgrade Installation is Not Working! :(

This is the error that I keep getting:

Warning: main(/home/talking1/public_html/journal/wp-includes/wp-db.php): failed to open stream: No such file or directory in /home/talking1/public_html/journal/wp-settings.php on line 69

Fatal error: main(): Failed opening required ‘/home/talking1/public_html/journal/wp-includes/wp-db.php’ (include_path=’.:/usr/lib/php:/usr/local/lib/php’) in /home/talking1/public_html/journal/wp-settings.php on line 69

Is there something that I overlooked
