feeding a helix in IE3D

good day,

i would like to model a helix in IE3D.
i am having a problem feeding the structure (or i believe i am)

for instance
helix diameter 1.5 inches
helix length 2.5 inches
segments per turn 12
number segments 24
start vertical length wire 150 mils
end vertical length wire 0
start angle 0
center x coordinate 0
center y coordinate 0
center z 10 mils

should build helix 10 mils above gp
(also made metal thickness to be 4 mils)

used select vertices to select the vertices at 10 mils
used add via on edges to build vertical rectangle from ground to beginnning of helix

used vertical localized port from 0 to 10 mils
i thought this would work
however after i saved i am not allowed to run simulation...

any ideas??

thanx in advance
