cant play Battlefield 2 MP

[Sierra1]

Hello!
I installed Battlefield 2 deluxe edition with original dvd after that i patched it to ver. 1.41,and i download the mini image to get it work without the dvd(because my friend has the orig. dvd and i give it back)I download the 1.41 server program and download the 1.41 windows server crack.I started a dedicated server but the server is still not cracked i've got this message: "your cd key is not valid!". My friend is able to join the server with his serial because it's orig. but i tryed to change my cd key with cd key changer and a keygen but still got the message...So what i'm doing wrong?
Because i'm sure i am doing something wrongSorry about my english I'm from hungary.
Somebody help me please!
Thanks a lot!
