Use the game updater to retrieve INCREMENTAL patches (if available) from the server.
Once downloaded, the file is copied into the game folder and executed. Be sure that
your firewall does not block the Updater or it will be unable to connect to the patch
You can also download the FULL patch from mirrors below.
Be sure to download the correct patch for your game version! If you download the
Starforce based patch version and apply to your Direct2Drive version, you will
invalidate your game and will have to re-install.
If you have the IGN Direct2Drive version, you can also download the patch from Direct2Drive.
Read this forum thread for more info on the different game versions or if you have the [discontinued] Trymedia version.
