You've installed the wrong area, methinks. You will find the OEM version (e.g. one which shipped with a images greeting card) that is really UK British, therefore you should have applied the actual UK/European patch wherever you actually live. Since the US and Australian versions make use of different copy protection schemes, updating the sport and among those patches can make this incompatible using the dvds you have.
Only option would be to uninstall X2 completely then reinstall as well as re-apply the right patch.
