Hello, so I just got the x56 H.O.T.A.S and I am trying to run macros on it for my pmdg 737. I am running into the same exact problem as this thread here https://forum.simflight.com/topic/84717-mouse-macros-not-working-with-pmdg-737-ngx/ . The problem is I have no clue what to do when I get to the actual sdk file. I typed in "file" in .h file but no instructions. My pmdg is the latest running fsx and fsuipc. I got some of the toggles working like flaps and such. But nothing like the Auto Pilot panel and over head panel will work.
