Highend Theme not Updating – Still on v1.0

I recently noticed that my Highend theme is not updating, and remains in the old version 1.0. The Theme doesn’t even show that there is an update available. I purchased the Theme on 5/25/2014 from MOJO Themes. I have the email receipt with transaction ID for proof of purchase.

Please provide guidance on how I should proceed to update to the latest version.

Thanks!
