script for 3dsmax

hi, i already follow some tuts here about importing in 3dsmax...already place the n2kmodtool.ms in the script/startup folder of 3dsmax...and when I open the 3dsmax...nothing happens...still can't read the .n2km files when importing..

I can't switch to blender..since I started long ago of using 3dsmax (not in nba 2k modding)....
need help pls..
