Brian,
Do you have A2A 3d Lights? If you have, try this new lights set:
[lights]
//Types: 1=beacon, 2=strobe, 3=navigation, 4=cockpit, 5=landing
light.0 =1, -17.990000, 0.000000, 4.930000, fx_shockwave_beaconh //fx_beacon
light.1 =1, 1.150000, 0.000000, -1.750000, fx_shockwave_beaconb_nl //fx_beacon
light.2 =3, -18.820000, 0.000000, 0.452000, fx_shockwave_navwhi //fx_navwhi
light.3 =3, 3.300000, -15.820000, 0.938000, fx_shockwave_navred //fx_navred
light.4 =3, 3.300000, 15.820000, 0.938000, fx_shockwave_navgre //fx_navgre
light.5 =5, 13.55, 0.00, -0.1250, fx_shockwave_landing_light_narrow_old
It´s using different .fx than the default package and because the problem has to do with the lights it might work.
