Before I read the link for the .zip file, I exited Dreamweaver and uninstalled Design Extender. Downloaded the latest version. Reinstalled design extender. Deleted references to Google script/map on page and created a new map. No help.
I put a second copy into the root of the web, because I wasn't sure from the post above exactly where the missing file was (the ... 's). No help.
Are there other things missing?
Why me? I have Windows7 64-bit, DW CSS5, and created maps with the stand-alone extension before (but uninstalled that extension before installing the combined Design Extender). I have these extensions installed:
Dreamweaver HTML5 Pack 1.2.7
Jeffrey Zeldman's Web Standards Advisor 1.0.2
Cookies Toolkit 3.1.3
Universal Mail 4.0.1
HTML Editor 2.0.2
Design Extender 1.0.3
