root file "<str>" no longer has its original name "<str>"

  Explanation:  The current root file name does not match the name
  used  when  the root file was created.  This could happen if you
  copied or renamed the root file, or  if  the  file  was  created
  using  a  concealed logical device name and that logical name is
  no longer defined.

  User Action:  Rename or copy the root file back to its  original
  name  or  location,  or redefine the necessary concealed logical
  device name in the system logical name table.
