I purchased a MegaScenery CD for FS 2004, installed it, and used their 2004->FSX converter FS2004FSXlibraryUpdate to make the scenery compatible with FSX. During the conversion, it said I must download and install a an updated FSX Terrain.dll file and a "Photo-Based Scenery Add-On Update". However the site referenced for these downloads, fsinsider.com, does not list them. I'm using FSX Deluxe (full version - can't find the version number). Are these two downloads really necessary; and, if so, can you tell me where I can get them. They're not at Microsoft.com.
