Battlefield 2 Invalid CD-Key

I got BF2 Complete Collection today and sadly i don't have a CD/DVD rom, so i called EA and the guy i talket to gave me the BF2 straight to my Origin, the thing is when im trying to play online it says "Your CD-Key is Invalid"

I've tried the so called solution but it didn't help

This one here

1. Click the Start button on the Windows Taskbar.
2. Select Run.
3. Type regedit into the available text field and press OK.
4. If you are using Windows 2000/XP/Vista/7, click on File, and select Export.
   Note: If you are using Windows 95/98/ME, click on Registry
5. Then select Export Registry.
6. Select All under Export Range.

If you have Battlefield 2 take the following steps (BF2SF check below):

    1. Type in x9392 and then your CD key.
       Example: x9392xxxx-xxxx-xxxx-xxxx-xxxx. YOU MUST INCLUDE HYPHENS
    2. If it’s the Digital Download of Battlefield 2 Complete Collection, your CD Key is contained in Origin under the Info Icon associated with the Game.
