I paid for an annual Navigraph Navigation Data subscription but when trying to access the charts I get " A Navigraph Unlimited subscription is required to use this application" Is that another subscription that I need to pay?..If so, what good is the Navigation Data?..any assistance would be appriciatted.
The data subscription updates the navigation data (waypoints, airways, etc) in whichever simulator you are using.
You do need a Navigraph Unlimited subscription to access the charts. The navigation data is included with a Navigraph Unlimited subscription.
You can see the Unlimited subscription pricing here: https://navigraph.com/pricing
