     The file that is corrupt is the LASTEXIT file for the particular
user.  This file is located in the first disk data area (listed as one
starts up aips but ahead of the messages you included).  Its name is

         SGDuuunnn,uuu;

where uuu is the user number in extended hex (EHEX UUU will tell you
uuu where UUU is the user number in decimal).   nnn is a sequence
number but the best bet is 001 for the LASTEXIT file.  Try just
removing that one and see how it goes.

      This corruption can occur if the user types exit and then at the
wrong moment does a Ctrl-C.
