[Zope-CMF] "editor can't find a valid editor for this file extension" when a ttempting to use webdav and Dreamweaver

[Slade Mrs A]

Hi,

It seems everyone else who has posted has made it further than I have with
Dreamweaver working nicely with CMF.  I get CMF talking to Dreamweaver, but
when I try to edit any of the page templates (i.e., header), I get the
following error with both Dreamweaver 4.01 and MX:

"editor can't find a valid editor for this file extension"

I have made the appropriate changes to Configuration/Extentions.txt: 
PT,HTM,HTML, ..... :All Documents
PT:Zope Presentation Templates
HTM,HTML:HTML Documents 

Can anyone provide me with some next steps?

Thanks,
April
