Danang and Khe Sanh Help Please

I downloaded and installed the khesanh.zip file here for the Khe Sanh airport with the dynamics. It does not show up in my Scenery list. I also got another file danang.zip somewher else from the same author (Owain. Danang does show up in my scenery list. When I try to run it FS2002 aborts. I tried contacting Owain at the address given for him but the e-mail was returned as an invalid address. Has anyone got either or both of these sceneries to work in FS2002? I do have all of the needed textures installed as far as I can see. Maybe Owain will see this post, I hope. Thanks, regards, Bob.
