I think you would need to be a lot more specific to get any real help:
what leap commands did you run? what files did you load? *when* did the
problem appear? was "segmentation fault" the only message? etc.

Asking people to "just change one Lysine with this one (use any text editor)"
is *very* ambiguous: I use Amber every day, and I can't figure out what you
really are doing that might be triggering a problem. What *I* would do to
"replace one residue with a modified one" is probably different than what you
have done -- which is why it is crucial to provide as much information as you
can about what you actually tried, and what happened.
