Hello Jie,
When I took the FSB Pro the first time I was very frustrated too because it is complicated. I think that is why the EA Studio came up to make it easier and simple, but I still have better strategies from FSB Pro..keep in mind that I use it for over 2 years now. Actually now I took 3rd license so I can run it on 3 machines all the time.
Watch the lectures from Mr. Popov that are free, and watch them a few times. The details do matter there.
Also, if you have particular questions, I will answer them.
