I’ve checked your account, you still have the support.
It is no needed to purchase the support (looks like the theme was purchased before the release of new Envato support policy that limited the period).
Please note that 1 license can be used for the 1 dev domain and 1 live domain. But keep in mind that you can use our theme license for 1 end product only. Read more – https://themeforest.net/licenses/standard
If you want to use our theme for more than 1 project you need to buy the individual license (on ThemeForest) for every project.
Have a good day too.
