AM2 Essence movment?

[Partonetrain]

Hey everyone, sorry to have to ask, but I can't seem to get my Ars Magica Crafting Altar to get essence.
Here's a pic:

I've tried over and over to link the nexus, conduit and altar with the Crystal Wrench but I just can't seem to get it to work. Is it bugged or am I just being a huge derp?

(Using Direwolf20 1.0.21 w/Zan'sMinimap.)

Does it need neutral essence rather than light essence? I've done that mistake a few times and it ends up looking like the nexus won't connect because of it.

Omigosh, thank you so much. I wouldn't have figured it out, thanks again.
