Any chance for an Orbiter2016 build ?
I have tested the SSRMSD in Orbiter2016 and it works BUT:
If you switch into cockpit-mode AND the HUD is on, SSRMSd.dll crashes orbiter.
So it seems to be that the HUD-overlay might causing the crashes, and it might be just a matter of re-compile against latest Orbiter SDK.
The problem is, the only sources I found are within the SSU-sources and here the SSRMS-source is pretty old.
I guess, that's the first version even without the nice controll-box.
Btw., I have had successfully converted the MBR_its-addon to vessel3.
So the HUD(power-output....angels) can be seen in D3D9-client via HUD, without the need to switch to GDI-compat-mode.
This works in Orbiter2016, too.
So if we would have the SSRMS, we would have something nice to carry and to construct.
