I've already had issues with Halo 3 in the games with gold promotion, which I just couldn't launch. Now I don't get any achievements for Hitman Absolution. Downloaded it a while ago, but now started playing- and none are unlocking. I've already 'subdued' countless guards, had an accident kill, hid a body, and none of these unlocked. Neither did the ones for progressing the levels. I've already reinstalled in the game and it's the same issue. What do I do?
