Template Editing in DreamWeaver MX

I found this neat free template:

http://www.r7designer.com/news/dw_templates/000061.html

and it gives directions how to edit it that seem like it's so easy.


But I don't know how to get to the point to be able to edit these, is anyone with more experience able to point me in the right direction here?

Most of the files I try to open in DreamWeaver give me a hard time, I think I am opening them from the wrong area by just clicking open? Also I am dumbfounded on how to get editable regions!

Help would be appreciated... Thanks!
