Hum, Jade, I'm ok to help you, but if you don't report the problems you encountered with the suggestions I made, then open an other (angry) thread to complain again, it's not going to be easy... [:(]

Are you sure that you didn't forget the hyphen in front of Dcom.eteks.sweethome3d.tools.temporarySubFolder....?
Without it, it can't work...
