functions.php line 16 ?

Hi, after I installed the update (i use wpfolio on wordpress), I get this every time I open my site or my admin:

Warning: require_once(/var/www/vhosts/karinazantinge.com/httpdocs/wp-content/themes/wpfolio/library/widgets.php) [function.require-once]: failed to open stream: No such file or directory in /var/www/vhosts/karinazantinge.com/httpdocs/wp-content/themes/wpfolio/functions.php on line 16

Fatal error: require_once() [function.require]: Failed opening required ‘/var/www/vhosts/karinazantinge.com/httpdocs/wp-content/themes/wpfolio/library/widgets.php’ (include_path=’.:/usr/share/pear;’) in /var/www/vhosts/karinazantinge.com/httpdocs/wp-content/themes/wpfolio/functions.php on line 16

Can someone please help? thnx:)
