Langin/Taxi lights in DHC6,Canadian Coast Guard Twin Oter

Hi:Sure hope someone out there might have a solution to my problem of no landing & taxi lights. The file is: dh6c_ccg.zipThis file requires d6sky42.zip installed. I've done that.I also reinstalled the aircraft. No luck.How can I completely uninstall this aircraft from FS9? Perhaps then, a new install of the same file would correct the problem.Has anyone elso had this same problem with this installation?Would appreciate any feedback from other members...any help at all.Thanks for your time.Regards,J N [email protected]
