No more lights #pc

Hi everybody,

actually I have a problem with the lights of most aircraft. Even if I turn on the Strobe, Beacon, Nav, landing and Taxi light it don’t light up. It makes some days I try everything but no changes, particuliarly on the A320neo and ATR72-600. I’m using them manually with the mouse. Tried to delete all in my Community Folder, but the same. Don’t know if there’s a link with the update 6?

Please, could someone help me?

Thanks a lot!
