Each purchase of Forest Pack gives you access to a single license for creating and editing Forest Objects, the full library contents, and free unlimited render nodes. For the duration of your maintenance subscription you are also entitled to premium technical support and upgrades.
The versions released during your maintenance subscription are yours to keep forever. If you like to stay up to date with the most recent versions of Forest Pack it is recommended that you stay on the maintenance plan, however there are no penalties for allowing it to lapse. If you want to skip some versions, it's no problem and you can jump back on at any time and download the most recent software paying only for another year of maintenance.
