                  New CONCENT.INS file

                  You will have to run a conversion program called USREXPND
                  (included in the Door ZIP file). This program is to be run
                  ONCE ONLY if you are upgrading from an earlier version of the
                  Door. If you do not wish to run the conversion program you can
                  just delete the .USR file (deleting the USR file causes the
                  game to start over with all prior scores being lost).
                          Type: USREXPND    in the Door directory
