First Of All, Please Don't Capitalize Every First Word.  It's Driving Me
Nuts - Thanks.

That error is meant for commercial applications.  You must purchase a
license of some kind to use these applications, after which your product
code (the serial number) is modified - and, due to the ROM-write "bug,"
could probably be modified by us if we wanted. When you try to run the
application without the right product code, the application will not run -
preventing pirating.  The product code is on Flash ROM but will not be
overwritten by Flash upgrades (normally).
