User blog:Yanxa/ME3 PS3 DLC install issue

I decided to treat myself to the complete collection for the PS3, and so I had to repurchase the DLC, which is fine. I'd made my way through most of the game (back up to Cronos Station), but am now unable to continue playing. Everytime I try to load the game, it tells me that "From Ashes, Citadel and Extended Cut are not installed". I've re-downloaded and re-installed them 3 times now, but it's still not recognising them. Does anyone know what the reason for this is, or if there's a work around?
