Win7 needs authorization. Have you tried to to see if you can save custom
keys while your in the game? While in the game hit the ESC key and enter
the Setting Menu and change some keys then go back in the game for a few
minutes and then exit the game and check the;
" \DirectX\DirectInput\User Maps "
folder again and see if it added any files
And also check to see that the folder names to make certain that they are
exactly like the folder names in the 7z file (if you did not to a drag and drop)
