How to reset iTunes Genius Mixes?

[caebrasil]

Hi,
My first post here. I' searching for a long time but any real answer for my issue.

I want to completely reset my Genius Mixes, from zero. I'm tired from actual selections...
I've tried to refresh Genius, but any significative difference, on fact is always the same results, same albums for each genre (jazz, r&b, rock, etc).
I've tried to deactivate Genius, then activate again, but iTunes always rebuild the same selections.
I know it's possible because when I bought my new Mac, before I restore my old iTunes data I activate Genius and saw a completely new and refreshed Mixes for my musics! But I restored my old iTunes and now I'm stuck on this.
I spend a lot of hours searching for a solution, without success.
Please, can anyone help me?

Nobody?
I was user of PC Windows, so I don't know Mac OS very well. So, anyone can help to figure how to clean up cookie, cash, temp files of iTunes? Maybe that's the way to clean any registered Genius Mixes information...
