Some time ago, we had "EZCA Simconnect bug". The reason - the code transition to windows11. We released EZsc_loader patch but this patch did not work correctly.
We fixed the simconnect issue for windows 11 users. Those who bought the product after February 1 already have all the necessary fixes in the installer. But there are users who upgrade from win10 to win11 - you need to download the latest version patch here:
FSX, FSX-Steam, P3D v.4.xx+
