Because this is from an older version of Legions, the file locations are slightly different for a few objects. So simply drag and drop the map files to your missions folder, then copy everything in the Interiors folder to your main Interiors folder (not into any of its sub folders). If you did it right, everything should appear normal and the map should run fine.
