Yes, go to your purchase history and you can download the update. You should delete the old version before installing the new. You should also add your support license key to the Connections : Settings admin page under the Licenses tab. You can get you key on the purchase history page too. When you activate the support license key on your site, you will receive updates in the WP admin like other plugins.
Hope that helps!
ps. The email address on your account is the same that you used for your last post. Just in case you need that to reset your account password. ;)
