I've made a clean install of the game and dropped your save in it.
When I load the save 40 I get the same result as before, with the quest being completed.
When I load the save 01 I get this
I've noticed that your save files are from V0.5.7.5(file01) and V0.5.7.0c (file40), but I'm playing on V0.5.8.5a.
That might be why I get something different than you.
But your save 01 seems to work with the newer version of the game so you might be able to continue from there.
I'm sorry but don't think I can help you any further than this.
