Guys, finally I resolved all.. now I can run NFSW Offline!!!
The problem was the "environment variables" for java, I had to check PATH (MatteoF50 helped me for this, credit to him).
I know that Windows XP is not Windows 7 or Windows 8/8.1 or 10, ok... but I can say that NFSW Offline runs very good on my PC
until now, I did not have any problem.. so I would say thank you to berkay and all the helpers, you made a great work and I wish you a good continuation for development and if someday we will have again Multiplayer Online, it will be fantastic
