deleted my profile - need to get to last level

[roflchopper]

I was a big fan of frictional games ever since and really enjoyed amnesia: the dark descent (I completed it in only a few days). When I heard there was a new campaign available, I immediately started the game. I then witnessed in horror, that I seemingly deleted my profile in the past and am not able to play the new expansion campaign.

Is there any way to jump to the last level, so I can defeat alexander, or can I unlock the justine campaign another way?
I don't want to play though the whole game now, as I am very eager to access the new content.
would really apprechiate any help
