Some minor corrections were done to the PHP pages of the Serial Number Validation system:

If you want to update the file on your server, please fetch the latest installer from the Customer Downloads area, then perform deploy the PHP files on your local computer (do not re-install, or you will overwrite your current configuration). Finally, replace serial_verify.php manually on your web server via FTP, renaming the file if needed.
