Help: All of my airport lights are missing!

My airport (runway, taxiway, apron, vasi/papi) and ultimate terrain enhanced lighting no longer appear. I first encountered problems with my lighting when I switched to a triplehead2go set up. All of the lights were too big so I fiddled with the light scalar settings in the [DISPLAY] section of my FS9.cfg (I've since abandoned the triplehead and removed the modified scalars). Sometime within the last week something has caused all of the lights to disappear completely. I've tried everything I can think of to resurrect them but have had no luck. Here's what I've tried.- Removing the light scalar entries from the FS9.cfg- Confirmed that the halo.bmp was not corrupted- Confirmed hardware lights set to 8 (I don't think this is actually applicable but I tried it anyway)Any ideas?Feel free to drop me an e-mail at [email protected].
