Still can't use Phalcon from Class 'Phalcon\\Loader' Fatal Error

I had a little trouble installing Phalcon, but now I think I've got things up and running and it appears to all be installed right (I think). I checked and the phalcon.so extension is getting loaded. I was just testing out the first tutorial and copied the code for the bootstrap.php file and it throws a 500 http error, and when I look at the log file it just says.

mod_fcgid: stderr: PHP Fatal error: Class 'Phalcon\Loader' not found in /home/user/public_html/index.php on line 5

Here's the code for that file. (line 5 is $loader = new \Phalcon\Loader();)

<?php
        try {

            //Register an autoloader
            $loader = new \Phalcon\Loader();
            $loader->registerDirs(array(
                '../app/controllers/',
                '../app/models/'
            ))->register();

            //Create a DI
            $di = new Phalcon\DI\FactoryDefault();

            //Setting up the view component
            $di->set('view', function(){
                $view = new \Phalcon\Mvc\View();
                $view->setViewsDir('../app/views/');
                return $view;
            });

            //Handle the request
            $application = new \Phalcon\Mvc\Application($di);

            echo $application->handle()->getContent();

        } catch(\Phalcon\Exception $e) {
             echo "PhalconException: ", $e->getMessage();
        }
?>

There just isn't enough noobs like me posting these dumb questions. I'm really interested in testing out Phalcon as a framework, just need to get the dang thing to work.
