You can download the files of your purchase during the first 48 hours. After that period of time the download link is not available anymore. The link will be available again if you renew your purchase or if you upgrade your purchase to subscription mode.
You can renew your suscription from here. Remember our suscription is valid for 365 days. During that period, you will be able to download an updated file every time you want.
If you prefer, you can purchase a new single update. It is cheaper than subscription.
