Suffering from the same problem like in the starting post of this thread, I did some anaylzes.
The error message I've got in the log file had the following pattern:
...

When testing the TBM with a clean X-Plane installation there were no problems at all, everything went smooth.
At the end the reason for my crashes was XPUIPC 2.0.4.8. When I use version 2.0.4.7 the crashes are gone so far.
Please be aware that the current version 2.0.5.9 of XPUIPC will break the IXEX737 (Throttles are not controllable anymore) .
Best regards,
Daniel
