Did you delete your profiles folder in the "my documents"? If not, do it .

Ok then try to delete it with ccleaner, or you can try it manually:

To delete the save files:

1. Open My Documents.
2. Right-click on the Battlefield 2 folder and choose Delete.

4. Open the EA GAMES folder.
5. Right-click on the Battlefield 2 folder and choose Delete.
6. Close all open windows.
7. Right-click on the Recycle Bin and choose Empty Recycle Bin.
to edit the registry and remove Battlefield 2:

1. Click on the Start button.
2. Click on Run.
3. Type regedit in the text field.

19. Close the WindowsRegistry Editor.
20. Go to the following folder: C:\Program Files\InstallShield Installation Information (If you cannot find this folder you may have to go to Tools > Folder Settings and click the setting to “SHOW hidden folders.”)
21. Find the folders with the exact same values as the registry keys above and delete them.
22. Empty the recycle bin once more.
