You may possibly be missing some objects that are embedded into those maps. If you can load the maps in your install then they have been installed properly, otherwise they would not show at all. It is usually missing objects that gives the problem you describe.

There is a tool that can check your static.ini file and see which objects in the map are missing in your own static.ini. These objects can then be loaded into your game afterwards.
