Hi!
Starting FSX with PMDG737 is no issue. However only as long as the CDU is NOT progammed with another flight other then the standard NGX flights. When preparing and flying a route, I can save this flight, but at FSX start-up and selecting this plane, FSX crashes. Also when I load the same (saved) plane from within FSX, after start-up with a standard airplane, it will crash.
So I can open FSX, as long as I do not select PMDG with a CDU containing a flightplan I made and loaded/saved in this CDU.
I use FSX Gold, with Accelerator or with SP1&2, no changes.
