I've been using Navigraph charts with MSFS 2024 for years now but lately, I can't seem to access the charts within the sim (specifically the BlackSquare Beechcraft Duke).

I've updated all my Navigraph databases but the charts button is grayed out on the GTN 750 I have installed in the Duke.

I feel like I'm forgetting something but not sure what...

EDIT: My license with PMS50 was expired, which explains the lack of function with the charts.
