Sometimes it is possible to use the later version of the Pack within an earlier version of Mathematica. When you open a notebook of a later version of the Pack into an earlier version of Mathematica and get messages that the notebooks (or palettes) have been produced by a later version of Mathematica than you are using, it often suffices to click on that warning window. What you might also do, is to save those particular notebooks again with your own system. Of course, all at your own risk. It is more complicated with the packages. If the engine changes much, the controls might not work.
