Data Assist fails - rsObj.options has no properties

I just installed Dreamweaver CC on a new SSD drive with a clean Windows 7 install in my existing system. Every time I try to run Data Assist it fails. It says
:
While executing timer in WA_SiteTools_ProgressV2.html, the following JavaScript error(s) occurred:

At line 1565 of file
[see attached image for full path] \Floaters\WA_SiteTools_ProgressV2.js":rsObj.options has no properties

I tried this using the default Orders and Products pages besides my own pages and it always fails the same way.

What extensions including the version numbers are installed?

the extensions that we offer that are compatible with DW CC are:
eCart 5.0.7
Free Tools 1.0.5
Design Extender 1.1.5
Data Bridge 1.1.4

and should be installed in the order listed above. You can try uninstalling Data Bridge and Reinstalling it, and also resetting the workspace layout:

go to Window -> Work Space layout -> Reset '<your layout name>'

and Delete the Dreamweaver Cache file from the users configuration folder:

I did all the above that Jason B. suggested and with no luck I'm stuck with trying to create a simple search and results page.

Is there a database connection defined?

Go to Windows -> Database to open the database tab and define a connection

if you do not have the Database access point, make sure that you have installed the Deprecated server behaviors extension:

I had to install the database access point and it worked!
thank you

OK, glad to hear it is working.
