I want to edit a Wordpress template using Dreamweaver CS5 and MAMP. I use this tutorial as a guideline to set it all up: https://www.youtube.com/watch?v=T_y0Gmsfqro

I get through setting up MAMP and defining the server in Dreamweaver. However in the end I get an error message that all necessary files cannot be discovered. I 'retry' and still some files are missing. I can see the website in Dreamweaver Live View, but DW will not allow me to change anything. I have run through the tutorial 3 times now. Each time deleting and downloading the Wordpress files and template, deleting the server definition, even uninstalling and reinstalling MAMP then start again and I still get the error. Any ideas what I am doing wrong?
