OK ,i did that and now I get the same error you got in your previous e-mail (so we are close). I am attaching you the file.(The original file had a dot before the name as you said) I should note that I had to change manually the USE_SHIPPED_BOOST to False. (I don't know if that played any part).
Thanks again,
Apostolis
