SPAD.neXt

I have just had to do a complete re-install from windows up. I used to be able to use the saitek multipanel with the PMDG 737NGX & 747-400 v3 but now they do not communicate with each other at all. I am aware of the numerous PMDG commands available in Spad Next (what would we do without it) however i am not sure of what commands to use and I believe there is a setting in one of the config files in PMDG planes but once again I am not sure, so I would be very grateful if someone could point me in the right direction. I am able to use the different commands in Spad Next for PMDG but I just need a point in the right direction.
Cheers

if you have still not sorted this out ... I posted videos on configuring with the PMDG 777 ... it always getting the board cast flag set in the SDK config ini
