I’m sorry for a delay. If you purchased plugin at our website you must have received a license key. So you need to to make sure your license key is activated to get notification about automatic update and run the updater.
If you purchased plugin at marketplace like Envato or TemplateMonster then you need to download newer version of plugin, unzip it and upload newer files of plugin overwriting existing ones.
You can contact our support team for assistance.
Note: we recommend to backup your files and database before update of any plugin, theme or WordPress CMS.
