Well i wasn't here back when 2012 demo came out so i had no clue :/
It really would been helpful if there was some Rules i could read somewhere, or did i miss them ?
I imported a 2011 track (Spa) into the 2012 demo and told people here how to do it and it was taken down. As far as I know the rules haven't changed.
Hopefully this clears up the confusion.
