Something has gone wrong with your save/get directory or LASTEXIT file
(did you say exit and then do a Ctrl-C?).

cd to your first data area

ls -l SG*

one of the files will be 65536 bytes long - that is the damaged one.
The directory is called

        SGDuuu000.uuu;

where uuu is your user number in extended hex.  It is not usually
65536 bytes long.  The others are SAVE/GET files and should all be
562176 bytes long.  Delete the bad one and start aips over again.
