This could be due to a permissions problem on the up[load directory.
To see if there is a PHP error occurring, add the following at line 1 of your poage:
<?php
error_reporting(E_ALL);
ini_set('display_errors','on');
?>
as for the progress bar, make sure the entire WA_DigitalFilePro folder is uploaded to the server, if you continue having problems, please post a link where I could see you page.
