This is a very strange error. You don't have anything weird like . Defined
in your path do you?

Try echo $PATH

How ae you running the dynamics? Are you using single processor or mpi? Also
are you definitely running the sander executable and not some strange script
that is called sander?

How about running the job without specifying any -x -e or -v flags and just
letting it use the default filenames. You can always rename them later. Do
you still get a problem?

I suspect something is very messed up with your environment. What machine
type are you running this on?

All the best
