This is one of the fundamental challenges of any mapping software solution - the real world situation changes continually and the software is always in catch-up mode. Upgrading to 2002 will definitely help as it provides maps that are at least one year more current, but obviously more ZIP codes have changed since the product was released.

Data currency is an even bigger challenge for a product like MapPoint that doesn't allow users to edit the base maps supplied with the product, or add other maps to the application.

In short, there is no real workaround.
