Problems with particle hair in cycles (2.72)

So I made some hair in blender using cycles and as soon as i hit animate (the play button in the time line) it strongly resembles her standing in a pool of water with a live overhead powerline in it.
Obviously I am missing a setting here some place.
(video included.)

Would you please attach the .blend file? That way it would be easier to find the problem out.

having problems uploading to the site. the blend file is sitting at 70mb not entirely sure why trying to figure a way to make it smaller but as i am still in the early stages of learning, haven’t quite learned those tricks yet.

Ok. have added it to drop box 9which untill now I never knew existed, have always transferred files via skype to those who needed them lol)

Turn off Hair Dynamics or if you need them try increasing the hair dynamics quality steps

Yup… turning up the quality steps solved it… Thank you for the help! No more electrocutions! lol
