I can't get autocomplete to work using database. I can't even click that option. I'm on DWCC2015.1

Using Dreamweaver CC 2014.1.1 release of build 6982. Specifically purchased this extension to autogenerate from database. But the "generate autocomplete from database" radio button is not clickable.

I can get the extension to work when generation is set to manually or to from templates. But I desparately need it to work from database. I know I have connected to the database because as a test I displayed data from the database on the same page.

Please provide solution advice.

Okay. So now, somehow, the autocomplete provider now default selects to "from database". However, selecting provider properties is now greyed out. Selecting OK without entering the database info gives the following error:

While executing onClick in Ajax Autocomplete.htm the following JS error occurred:

At line 1090 of the file "...Commands: Ajax Autocomplete.js": selConn.options[selConn.selectedIndex] has no properties"

If someone can tell me how to hardcode the database provider properties information into the file that would be fantastic. At least then I could hack the extension and get it to work. I am desperate!
