(Read-only Information. I could give more information, but I don't want that every wannabe is able to fake his own reg-key...). Don't touch the other bytes.

   +0    50 BYTEs       Name of user
  +50    50 BYTEs       Address of user
                        These values are entered when registered Winplan is
                        run first after registering. Both are encrypted by
                        adding 13 to the ASCII codes.

                        - 13: key is valid
                        - 666771: key is valid, but must be unlocked by
                          filling in the form displayed when Winplan is run
                          (above fields are invalid in this case).
