put the files in your "C:\Dokumente und Einstellungen\All Users\Anwendungsdaten\eSim Games\Steel Beasts\maps\height and C:\Dokumente und Einstellungen\All Users\Anwendungsdaten\eSim Games\Steel Beasts\maps\terrain" folders. Note: look for the exact folders (All Users!!!) Edit: if you cant find the folder do a windows search and look for *.hgt and *.ter files... it will lead you to the right directory greetz Kama
