Troubleshooting Coursebuilder installation in Dreamweaver MX 2004

Coursebuilder is a Dreamweaver extension that creates learning interactions, like quiz questions. When I installed the extension in Dreamweaver MX 2004, it seemed to work fine, until I got to the point of using the Actions manager tab in any given interaction. then I would get an error message that said

“Actions Manager Data was invalid,” then another dialog came up that said

“While executing onLoad in CourseBuilder Interaction.htm the following JavaScript error(s) occurred:

“At line 141 of file “MyHardDrive:Applications:Macromedia Dreamweaver MX
2004:Configuration: Shared:CourseBuilder:Scripts: amTreeClass.js”:TypeError:tr
eeData[chnkStart[0]]has no properties”

Coursebuilder worked properly only after I reinstalled DWMX2004 in my USER Applications folder (HD:Users:UserName:Applications). In this configuration I found I could not use the Extension Manager that was installed with the new instance of DWMX within the user/applications folder. When I would navigate to it using File:Open from within that instnace of Extension Manager, it was grayed out.

To get around this, I doubleclicked the Coursebuilder .mxp file itself, and let it open whatever ext. mgr it wanted. It did then show up in the new DWMX application when I opened that instance, and did indeed work completely.
