GoFlight MCPPRO doesn't display, only zereos appear when flying the PMDG 777

[MsThang]

A while back I somehow resolved the problem I had with the PMDG 737 where the GoFlight MCPPRO only displayed zeroes even though the knobs turned and did affect the MCP, (autopilot). I can't remember how I fixed it, but I remember that I had to edit a file and add a line to make it work. I have no idea how I resolved this before.

 

I am again having this problem, this time with the PMDG 777. The GoFlight MCPPRO displays only zeroes even though I can turn the knobs and see the PMDG aircraft being affected by my inputs. I use SPAD.NEXT and installed the program that should work with this. I also have FSUIPC7 installed, but I have never used it and don't really know that program.

 

Please help if you have any ideas.
