My first observation is that your soil conductivity is zero.
Should always be zero (GN card should be: GN 2 0 0 0 12.0000
0.007).
I am certain that this would give you the kind of error messages
you are seeing. The program actually runs under these conditions, using
Nittany's NEC-Win Pro,
but produces erroneous results -- input impedance, radiation patterns etc.

Correcting the conductivity gives much more realistic results: resonant at
6.8 MHz,
Zin 700 ohms, classic dipole pattern.

Your segmentation is probably a bit low for such close proximity conductors,
also
the segment sequence could be improved, but not important unless you want to
graph the conductor currents. I would suggest making the conductor segments
equal to the triangle side lengths. This may change the results a little,
but the
correct sign for conductivity will make a big difference.
