So, it said achievement unlocked, but then you didn't get the achievement, because it became Trial version? If that's so, then I don't know about the achievement. I think, in that case I would maybe delete and redownload the game, after you got the 1000 sharks. Often this process deletes the counter, so I would do the 1000 sharks before taking this in consideration.
