In order to fly a real flight plan, or at least an updated one following authorized airways, actual VOR, or if you plan to fly a departure / arrival procedure as published by online Aeronautical Services, then you need your aircraft FMS database and flight planner software to be updated.
Navigraph does that. Download the respective Airac Cycle update for any of your addon software from Navigraph, see the pricing here. Interested ? Purchase coupons or use your remaining credits (old payment system still available for almost 9 months).
