Minecraft disappeared from ps3?

So, a while back, I bought Minecraft from the playstation store. Everything was fine and dandy for a bit, and I was able to play it with no problems. But then, one day, the game disappeared from my ps3! The save data, cache, tutorials, unlock code, and options are still saved on the ps3, but I can't find or play the actual game anywhere! I've tried re-downloading the game from the Playstore, but that doesn't seem to change anything at all.
