Scenery Crashing FS9

Hi everyone,I'm not sure this is the proper forum, but if anyone can answer this question, you're the ones. I recently added the Suisse 2004 airports to FS2004, which are excellent BTW, however, when I try to fly out of or into Sion, FS9 just quits and dumps to desktop. I am quite sure I have all the textures (Nova, Novagold, VOD, Airport) but would it be a missing texture issue? BTW, Sion is fine in the standard FS9 build. I should also note that I have this same problem with Juneau, Alaska in the default FS9 build.Any help would be appreciated, but I know I can always just remove the Suisse 2004 Sion if required to fix it.Thanks.
