Javascipt error - While executing timer WA_SiteTools_progressV2 htm, following Javascript error(s) occured:

While building the "Product Catalog" portion of a site I am continually getting a java script error ... "While executing timer in WA_SiteTools_progressV2.htm, the following Javascript error(s) occured:

At line 123 of file .... " (See attached)

and leads to a file in the AppData\Roaming\Adobe\Dreamweaver CS6 Floaters folder WA_SiteTools_ProgressV2.js Col has no properties

I have created the products administration pages and the user administration pages with no issues. I also created several other admin pages to edit several tables on the database without issue. Then I get to building the Product Catalog and I am stuck with this error.

Based on the posts I have read I have uninstalled data assist several times and re-installed it making sure I have the latest versions (data assist and ecart). I have deleted the .dat file on Dreamweaver after each fail of the product catalog so I have a fresh start each try.

Error persists. Basically the builder starts to create the catalog and hangs on the results page and then the error comes up. Once I hit OK is just stalls.

I am on a PC with a WAMP install. I have tried the install while on my PC and connected to the test site.

Any ideas on what could be causing this?
