Hi Tonny
I did a bit of a search for you on that website and I could enter the kuid number you provided. It came back null. It does not exist. Probably superseded with a new kuid but we have no way of knowing what that is.
By entering the first part of the kuid I found 3 German engines that used this author (376111) and all relate to a corona. I thought this was the case. Probably a red or white as it is an engine.
What I would suggest to you is search through your engines (one of your engines will not be showing a red or white light in surveyor)
From another similar engine look at the config file and see what coronas are being used there. Copy and past that kuid number into the config of the engine with the missing lights and delete the "missing asset" kuid from the mesh AND the kuid table at the bottom. You will not find that missing asset that you are looking for and the only way to fix this is to use another working corona from another asset. Then your engine will work as it should and your "error" will go away.
It would help if you could tell us what asset it is that is throwing up the error.
Best I can do at the moment.
Regards
Doug
