For Config Editor:
Open the Config Editor.exe file within the download and then if its the first time, it will ask you for the cricket_pc.gob file. This is located in the C:\Program Files\EA Sports\Cricket 2004\Data' directory. Select it and the window will return to normal and the box near the GOB will indicate the file which you selected just now. Now to import an AI patch you downloaded, extract the patch to a folder you know, click the Import button in the Config Editor, select the patch you extracted to ur folder and it will ask "Do you want to Import the so and so patch', hit Ok and you're done. But before importing, be sure to Export ur original AI patch in case you want to restore it back (if not, then you have to re-install Cricket 2004 back again!). Use Export and select a folder where you want to save the Original AI patch to and hit Save and you're done! This is for the config editor. Rest, I will post when i get time or some one will help you here!
