Lighting problem

[XLR8]

Hi all

I have not had any problems with FSX in a while until today.The problem is that the nav lights and effects are square now rather than normal lights or smoke.How can this be fixed. I thought maybe it was a driver so uninstalled and reinstalled it. Thanks

Did you recently install a third party aircraft? I had the same problem with Thomas Ruth's Airbus A330/A340. Look to see if their are some effect files that you didnt install, their is a folder in the effects main folder named texture, some aircraft add ons need to have some files copied into that folder. Hope this helps.
