I am using OpusFSI as a weather engine and camera system together with FLS A320 X. That is no problem, if you disable DHM (otherwise landings are problematic).
Recently, I added your Spotlight program to get dome lights. It works fine. But the simulation (FSX_SE) now crashes when OpusFSI is started. When I uninstall Spotlight, everything works again. I wonder if you know about this conflict.
I already contacted OpusFSI and they cannot imagine what could cause this. They asked me to contact you.
To be more precise: I load the FSL Airbus in the free flight menu, start the flight, wait for the countdown, then start OpusFSI. Then it crashes. It also crashes with the Aerosoft Airbus in the same way.
Can you help?
