csv file

I am trying to start a new test forum on my localhost using the members list from my wokring forum, I am making a new site to upload after I finish and replace the old forum with the new one

I have downloaded a members csv file from admin when I click to upload it, it doesn't seem to put any members or anything into admin. am I doing something wrong? can some one please guide me on how to do this please .The image I uploaded here is what I get and it goes on for hours just redirecting.
