having difficulty

Hi, I am new to n-track, I have been trying to save an Mp3 copy of my recording, but was asked to download lame encoder, I did that but still whenver I try to save (mp3 format) I get the same message saying:
Download Lame OR Locate Lame
can anyone please give me step by step instructions how to resolve this problem, many thanks in advance, Ash

You need to tell n-Track where lame is. Settings > Preferences > Paths > Locate LAME.
