I have Universal Email 4.0.1 and Data Bridge 1.1.2 installed 
This is the problem.
Data Bridge includes the functionality of Universal Email. You should not have both Data Bridge and Universal Email installed.
Uninstall UE and Data Bridge, then reinstall Data Bridge, and install the latest version, 1.1.3.
Design Extender includes the following extensions:
Design Extender
-- CSS Sculptor
-- CSS Menu Writer
-- Framework Builder
-- PowerCMS Builder
-- Pro Maps for Google
-- Site Import
-- Site Sculptor
-- Social Media Toolkit
If you have any of those stand alone versions installed, they should be uninstalled before installing Design Extender.
Data Bridge includes the following extensions:
Data Bridge
--CSS Button Styler
--CSS Form Builder
--DataAssist
--Digital File Pro
--Dynamic Connections
--Dynamic Dropdowns
--Dynamic Web Charts
--Form Toolkit
--HTML Editor
--Image Resizer
--SecurityAssist
--Universal Email
--Validation Tooltips for Spry
If you have any of those stand alone versions installed, they should be uninstalled before installing Design Extender.
