Doesn't Initiate Fatigue Analysis

Hello,

I'm using Creo 3.0 M060 Academic Edition.

I'm following a tutorial from my Precision PLM account, but I found a problem in some of the steps. A similar video is this:

learningexchange.ptc.com/tutorial/3552/fatigue-analysis-with-multiple-load-sets

What happens is that when I click in the New Fatigue... button, it displays this (See figures). So in a few words, I'm unable to perform this type of analysis.

*I have to say also, that I already tried to perform the Static Analysis first and then come back to the New Fatigue... button, but the result is the same.

So, how could I fix this?

Thank you.
