I think it comes from another plane used just before. I just solved the problem after a reinstallation, miraculously after the third time it is currently in operation.
But there is another problem with the hydraulic switch pump, he must be off otherwise it starts of its own. The rest seems to work properly. It remains to see the flight.
Edit :
Well there is too much problem on XP11, during the flight my instruments are extinguished, the autopilot had problems maintaining altitude.
I go back to the XP10 version and wait for the XP11 version.
Thank you and sorry for the inconvenience for this test.
