Aircraft Lnanding/Taxi Lights-Problem

The aircraft landing and taxi lights only work in the VC cockpit mode.In the 2D cockpit mode the runway in front of the aircraft remains dark. This applies to all aircraft.I installed a freeware software that changed the way navigation lights blinked, and I also installed freeware software that changed the intensity of the landing lights. However,everything worked will after these installations. It was only recently that I ran into this problem. Does anyone have any ideas?Is there anything in the CF9 cfg file that I need to look at?Thanks,Stanner
