This will never work, since nmode doesn't know about generalized Born
solvation. You could look at NAB ( -- of course
at the expense of learning a different program.

This won't work. It could be that combining "dielc" with igb=1 is causing
your structure to fall apart. Setting dielc to anything other than its
default value of 1 is very dangerous for nucleic acids.
