rsrbr2015 install help

Hi there, new here and relatively new to Richard burns rally and need a little help setting up rsrbr 2015.

I downloaded the game,updates, tracks and cars here; http://forum.rallyesim.fr/viewtopic.php?p=181480&f=38#p181480

I followed the instructions to the letter. When I get to the tracks part, I downloaded the 7 files and left them in the same folder, when installing the tracks i get an error message C:\Users\Kati\Desktop\rbr\Richard Burns Rally\Maps\track-41_M_textures.rbz...
