I started playing the game a year or so ago, then stopped for some reason. I got a few of the early achievements then, but now that I'm playing it again, none of the achievements after the ones I got are unlocking. I tried uninstalling and reinstalling the game, but they're still locked. Has anyone else had this problem?

I've also had this problem.

I'm also having this problem, beat the whole game and not a single achievement unlocked for me.
