Hello,
All of our premium themes come with the initial 1 year of Subscription i.e. you can download the updates till 1 year of purchase date. But after one year, you will need to renew your subscription in order to continue downloading updates.
For the renewing process, you have to simply buy the new theme and use the license that you get from the new purchase.
If you’re unable to access to buy the license, email: info[at]themepalace.com
Regards.
