If your LeMans track is located inside a folder called
GTR2\Gamedata\Locations\LeMans V1.0 for GTR2 by the modder\Gamedata\Locations\LeMans,
or something similar, then yes, you are doing it wrong.
Read and follow the included 'readme' file, and follow it
explicitly. Generally once unzipped only the folder containing
the track data is copied to the 'Locations' folder.
