Hi Iván,
Please ensure you have the latest FF A320 version 1.1.9.
The manual mapping in FMS Data Manager for the FF A320 is incorrect. I suggest you start afresh:
Please disable any Antivirus and firewall.
Please use Windows to uninstall FMS Data Manager. Specifically use FAQ - Charts desktop installer fails immediately .
If they exist, please delete folders:
c:\ProgramData\Navigraph\FMSClient and c:\Program Files (x86)\Navigraph\FMS Data Manager.
Please download and install latest FMS Data Manager .
In FMS Data Manager Settings tab check your X-Plane 11 path is correct.
In Addon Mappings tab your FF A320 should have Automatic mapping
<XP11>\Aircraft\Flightfactor A320 Ultimate where <XP11> is your X-Plane path.
If not, select and Remove that entry and press Scan and Save.
Please let us know how you get on.
Cheers
Ian
