Help! I can't get fur to move with hair!

[phalimjinx]

I have an old file that I'm trying to update.

Originally I had a set of dynamic hairs that I used to move cylindrical geometry. Worked fine.

Now I'd like to trade out these cylinders for fur.

I've set up the fur on a plane, I select the hair system, do a "Attach Hair System to Fur - furDiscription1"

I can see the "FurCurveAttractors1" node in the Attribute Editor, but when I play through the animation the fur doesn't move. I've tried this on a brand new scene and everything works fine. But for some reason the scene I need it on won't work.

Anybody know why this is happening? Is there a solver that's not linked up or something? Any suggestions?
