I finally solved my problem, the support service of Eqoon is awesome!
They eventually realized that the programm doesn't work with the German version of XP (I live in Germany).
So if you are interested in some of the videos and it doesn't work for you, don't hesitate to contact eQoon, the guy gave me a trick and it works fine now. The link of the video service is: http://www.eqoon.com/fft
(they also have portraits of Gasquet, Sidorenko, Chardy, Roger-Vasselin...)
Gael's technique is... a bit awkward!
