Error On Set Purchase Code

When I activate the plugin with the Purchase Code it shows the image error and my wp-admin stops working. I have to delete the plugin for wp-admin to work again. All other plugins work correctly on my WordPress. 777 permissions on all folders and wp-config.php is already:

define(‘FS_METHOD’,’direct’);

Still the problem continues. How can I solve?
