1.  Copy *.B from DBAMFG to new DBAMFG\DEFAULT folder.
2.  UT-D, click Chg All Locations, enter DEFAULT\ as the new Location and B{space}{space} as the comp code.
3.  Delete the *.B in DBAMFG EXCEPT do not delete FILE*.B, ERRMSG.B, USERS*.B
4.  Load the program and make sure the data is there and any other companies also are accessible.
