curve network force eq length doesnt work in gh0.8.0063?

Hi,

I tried to solve this with geomgym: http://www.grasshopper3d.com/xn/detail/2985220:Topic:501580?xg_sour...

and use the "curve network force eq length" component but its not working in gh0.8.0063... maybe im doing something wrong but the second example here: http://geometrygym.blogspot.com/2010/09/grasshopper-curve-force-den...

doesnt work either (i replace the old component with the new one too), so im thinking that its because grasshopper version.

I tried the curve network force density component with equalize length true, but it doesnt produce equals lengths...

the red error panel say something about index out of range...
