I bought the Steam version of Final Fantasy XI: Ultimate Collection Seekers Edition a while ago and from what I remember the Steam version of the expansion files is US whilst the base game is EU or something like that. I know that to fix it there was an official file somewhere with the EU files to patch the expansion to EU but I can't remember where I found it.

Anyways I've had to do a complete reinstall of FFXI and when I reach the accept terms window it tells me "expansion pack data has not been installed" because of the issue I mentioned above with the base being EU and the expansion being US. I was wondering if anyone remembers where the patch files are so I can begin playing again?
