Metal Gear Database

Some of you may have heard of the Metal Gear Database. Click for info.

It's basically an MGS encyclopaedia covering every canon-game. It's available on the US and Jap playstation stores but you can't get it in the Euro store yet. Word has it we'll see a release on the 26th of June. I nabbed it using my US account but unfortunately all of the MGS4 data is locked since my MGS4 Euro save isn't compatible. Has anyone found a work around to unlock the MGS4 content yet?

I've tried to download a US save file, which didn't work and then I downloaded a MGS Database save file that'd been unlocked, and even that didn't work. The 26th release date isn't confirmed for Europe, or at least that's what I've heard, so I'd love to get my hands on an unlocked Database somehow.
