I received the email with the complete game. Absolutely amazing thank you. However I had to restart my computer and when I load the game now I can not enter multiplayer cuz it says my cd-code is valid. Anyone out here who can help??

Do you still have the setup files?

Try to download this executable and run it:
http://bf2hub.com/downloads/invalidcdkeyfix.exe

After that, you should be able to find the BF2KeyMan executable in the setup bundle.
Run it but as administrator, by right-clicking it and selecting "Run as administrator".

Generate a random key, note it down for later use and apply it.
Then try to join the servers again and you should be good to go.
