Help! Porting v.9/v.8 planes to v.10 and making lighting work.

Hi,I have ported Jaques Braults nice DC-6 from version 8.64 to v.10 by first letting v.9 Planemaker convert the file from 8 to 9 and then letting v.10 Planemaker do the rest. Had to do some minor stuff manually to make it work but its good now... for the most part. I still have one problem:The landing lights won't show up. The switch is present and there is a slot assigned to the landing light in the appropriate menu in planemaker, but it won't light up. Strobes, Beacon and NAVs do work, although they won't light up the fuselage (should they not do that automatically with version 10's global lighting?).Any ideas. Appreciate any help :-)Thanks
