JohnJohnJohn is correct. Some of the paks will have had corrections / additions / bug fixes etc over the years. Installing everything over the top of your existing installation will do two things:
1: Give you all of the latest purchased paks.
2: Upgrade any existing paks that might have been amended since they were first installed.
