(1) make sure your default shell did not change.
    [you have a sh or csh script above. You can cat /etc/passwd | grep mike
    assuming mike is your username. The last entry should be the shell
    you are running... If it is not /bin/sh, csh, or tcsh, you can start
    a csh shell by typing csh]

(2) type "which sander" to make sure that sander is in your path

(3) make sure that the "mdin" file was actually created. In general if
you use a script and there are problems, try doing each step by hand to
make sure all is well. If this is in a script, make sure

#!/bin/csh

is the top line or whatever the path is to the appropriate shell you want
to apply.

This is likely a UNIX problem and not a sander problem.

Good luck.
