The license you’ve purchased from Envato was active for only 6 months, so it has definitely expired by now (we removed the product from Envato in January 2015). For this reason, I cannot offer an exchange for a new license.
The version of the plugin you must be using is at least 1.5 years. I strongly recommend that you purchase one of the licenses from this website and enjoy the latest version of the plugin because a lot has changed and tonnes of bugs have been fixed. Additionally, it is compatible with the latest WordPress 4.7.4 and you will gain our prioritised support. We will be more than happy to install the plugin on your website for you, too.
Could you please open a new ticket explaining your issue in details? I will then do my best to help. Otherwise, the thread opener will keep getting e-mails regarding our conversation, which doesn’t relate to his case.
