It happens if you provided invalid purchase code during installation. You can fix it by getting your purchase code as shown here

After you get it, just modify the config.php file from where you installed SMS Gateway admin panel. Change line looking like the following one.

define('PURCHASE_CODE',  'Enter your Purchase Code here');
