There are newer versions of Data Bridge and Design Extender available.
You should uninstall Design Extender and Data bridge from the extension manager, then log into your account to download the most recent versions and install them
after installing to the extension manager, start DW to launch the WebAssist installer. If the WebAssist installer does not launch automatically, open a php page to force it to start. make sure to restart DW after the WebAssist installer completes.
The Insert -> Forms access point is a built in Dreamweaver function. That is not an access point that we added. if you continue to have a problem, you should contact Adobe for support
