Before printing out the error message listed above, LEaP will also print out a
error message telling you what the real problem is, such as missing
parameters, etc. You need to look at that message.
[The most common reason is that you did not load a frcmod file for the Na+
ions; see the section on "Ions" in the "Choosing a force field" chapter.]
