Check and make sure the cd key is correct. You can do this in the registry I will post exact instructions when I get off work.

reading around they say if your running on windows vista or 7 while trying to play multiplayer you must click run as administrator or it supposedly gives you invalid cd key error.

Anyway they also say to register the game because then you can validate your key through the ea support website.

1.) open your c: drive and search for BF2CDKeyCheck.exe

2.) copy that to your desktop.

3.) Open computer>Program files>Ea games>battlefield2> support.

4.) copy BF2CDKeyCheck.exe into the above.

5.) Re enter your bf2 registration code.

6.) Run BF2CDKeyCheck.exe


8.) Re enter your bf2 registration code

9.) Run BF2CDKeyCheck.exe

no all i had to do was go into the reg edit and add his CD-key in there and it works now

I was gonna suggest that but they stated they encrypted the keys with the new 1.5 patch so I didnt know if it would work with 1.5 lol
