In tablet of MSFS2020 I only receive DEMO you need a subscription...but no charts

I new in NAVIGRAFT. I think that I download all that I need to use it (my subscription is complete). The problem is with the tablet into A320 FlightByWire. When I ask for a chart of any, I only receive. DEMO yoy must have an ultimate subscription, and I´ve it today 1 month. Please I need help. Thanks
