A simple question, when? :)

I have finished the game and replayed it two more times to get all the achievements, but the last achievement 'One of a kind - Unlocked all the other Achievements.' hasn't been given to me. I heard that you had to do all the achievements through one game slot but I found that difficult to do. I really would like the last achievement! Thanks....

How am I supposed to get play all the hidden objects puzzles and play all the pair matching games achievements on one file? Lame.

I now have 34 out of 35 achievements and somehow I didn't get the last one that literally requires 34 out of 35 achievements. Have tried restarting the game. I did use several different "accounts" and got the 34th achievement with my third one, maybe that's the issue?...

I don't mind at all playing a woman as a protagonist, but I was curious if there were any Artifex Mundi HOPA where you played a man.
