Availability problem on DLC (PS3)

Hi, I've already played through the game twice and now I want to check out the DLC. The problem is, I can't find it on the PS Store. Is there some region issues on this? I think my game is EU version because the activation code brought me to the EU page of Square Enix, and then my PSN account is set on HK, although I use/play with this account both in Japan and the Philippines (in which I travel to back and forth). Uh, I know this might be a stupid inquiry but I really have no idea why I can't find it and I really want to try out the DLC. I've searched and inquired for days in the internet but to no luck. Can someone please finally enlighten me on this? Thank you!
