Event Calendar 6.4 error

I’ve just installed the Even Calendar plugin (http://wordpress.org/extend/plugins/events-calendar/) but keep getting the error:

Warning: file_get_contents(): URL file-access is disabled in the server configuration in /home/domains/thegildedpen.com/web/wp-content/plugins/events-calendar/ec_calendar.class.php on line 42

Warning: file_get_contents(http://thegildedpen.com/wp-content/themes/gilded1/style.css): failed to open stream: no suitable wrapper could be found in /home/domains/thegildedpen.com/web/wp-content/plugins/events-calendar/ec_calendar.class.php on line 42

I’ve put in the code shown on this post (http://wordpress.org/support/topic/179911?replies=11) but I still get the error. Anybody have any ideas or know of another event calendar?

Thanks!
