All licenses come with one year support and updates (or 2 years in case of "2 years subscription").
If you have made your purchase more than 12/24 months ago, your license is no longer valid for the latest version (version 3.0.12. was released in 2012, 3.0.16. in 2016).
We offer 20% discount on license renewal. You can read about our renewal & upgrade policy here: https://www.limilabs.com/purchase/renewal
