Events Calendar Error Help

Hello All!
I was hoping that someone could help me with a issue I am having with the Events Calendar plugin. After Installing the calendar and then adding the widget to one of my sidebars I recieve 2 sets of warnings. They are as follows:

Warning: file_get_contents() [function.file-get-contents]: URL file-access is disabled in the server configuration in /home/.capitalizers/usavtours/usavtours.com/wp-content/plugins/events-calendar/ec_calendar.class.php on line 42

Warning: file_get_contents(http://usavtours.com/jellegooddemo/wp-content/themes/wp-delicious-restaurant/style.css) [function.file-get-contents]: failed to open stream: no suitable wrapper could be found in /home/.capitalizers/usavtours/usavtours.com/wp-content/plugins/events-calendar/ec_calendar.class.php on line 42

You can see the actual errors here http://usavtours.com/jellegooddemo/

Any help would be greatly appreciated. Thanks!
