It seems that the Illuminati exploit doesn't work properly if your PSP is set to non-English settings. At a guess, it's something to do with unicode when displaying the profile name.
Anyway, if you are having problems, especially with the European Lumines, then try switching your PSP to 'English' settings.
One other note - Lumines sales on Amazon.com have gone up over 14,000% since yesterday!
