wp css problem

I’m having problems with my wp 3.01 site. I adapted kubrick which worked on a previous blog on wp 2.82 but here the css won’t recognise the div content or classes narrowcolumn or post is it that it’s on 3.01 and incompatible or is there something wrong with my code. I took out most css using those id and classes the site is at http://www.culturaldissection.co.cc
