Dear Dean ,
Thank you for your recent email.
We would like to apologise for any inconvenience you have experienced, but would like to advise that the American PS Store has been out since November '06 and has therefore had much more time for updated content to be released and programmed for themselves, in Australia we are under the PAL/European region whereas our Store needs to be updated via the UK who need to release the Data under the many different locale's/countries/languages of Europe which can unfortunately take much longer for our developers to code, we are striving to get the downloads released world wide simultaneously and appreciate your patience in this matter.
Regards,
Krystal
