If you mean the problem with the shadow textures in the baggage train, that's surely a video driver problem or a video driver setting wrong or an FSX setting wrong.
- Update your video driver
- Reset your video driver settings to default
- Reset the FSX.CFG to default, by removing the %APPDATA%\Microsoft\FSX\FSX.CFG file
- After you reset the FSX.CFG file, be sure the HIGHMEMFIX tweak is set to 1 (you can set it directly with the Addon Manager)
