Welcome to the community portal. About your problem, I have not used that guide you link to myself, instead I used the following quick guide here http://share.ez.no/forums/general/how-to-begin-with-ez-publish#comment57338
That was with succes, editing the files showed the changes I made directly in the front end of the site. Might be worth checking if that works for you as well.
