[Centos] anaconda in 3.3?

Greetings,

I'm using centos3 to study for rhce, centos came highly recommended in Michael Jang's rhce study guide. I've been having trouble isntalling via nfs, an early exercise in the book, and googling around leads me to think it might be an anaconda bug. I tried following the anaconda link on the "upgrading from 3.1" page but it's actually a duplicate of the anacron link. Does anyone know if this update addresses anything along these lines? Is there any way of guessing whether an update should solve my problems, or that a full re-install with freshly downloaded 3.3 isos would be better?
