FSUIPC Connection Failed

[Daedra]

Hello,

I want to use FSXWX and I did install as website said.

I've used it before. It was working fine. Now I installed it again. I runned FSXWX and FSUIPC by admin. But it says this;

"Auto connect attempt
SIMCONNECT connection established
FSUIPC connection failed
Connection closed"

I am using P3D v4 and downloaded FSUIPC5 5.122 .

P3D v4 not open when I install FSUIPC. What's wrong with me? What should I do?

Please help me, thanks..
