I downloaded the file and looked through it. It doesn't appear to be any different to mine. Even I have the same warnings and error.

These are yours:


30:01:2022 22:25:54 | Warning : 1:0 : csFormEmailOnline.nsh[22.9]
30:01:2022 22:25:54 | Warning : Error 1 Incorrect function.

30:01:2022 22:26:02 | Error detect Firewall on this connection!



These are mine:


31:08:2021 13:38:16 | Warning : 1:0 : csFormEmailOnline.nsh[22.9]
31:08:2021 13:38:16 | Warning : Error 1 Incorrect function.

Yet it works fine in FSX/SE/P3D3
