Okay, please help me. I'm about to tear my hair out.

When I use the ICM trainer (now I think I've already asked this, but I didn't get answers which satisfied me, so please forgive me) and read the articles. I cant find anywhere which EXPLAINS the ICM to me. When I open it up and start a session (oh also let me say that the "light" trainer doesnt work on either of my computers, only the full one) It asks questions; now what confuses me is this: Am I supposed to learn by trial and error? I feel like im trying to learn Spanish from someone who only speaks Spanish. Is there an article somewhere, which describes the ICM, exactly how I'm supposed to learn what to do in certain situations... I apologize for my fragmented thought patterns as I'm quite frustrated. :P

EDIT: Problem sorted. This is what I get for not sleeping enough. Thanks to everyone who took the time to look at the thread.
