Hi, When did you download and install eCart. I am aware that there is a newer version of eCart that was uploaded recently..however it kept the same revision number then the previous. it was more of a hotfix. but always worth trying that. Also have you tried deleting the file WinFileCache-########.dat file this file is located at: (for example on my own machine)...
C:\Users\Christopher West\AppData\Roaming\Adobe\Dreamweaver CC 2014.1\en_US\Configuration
(make you you have selected show all hidden files and folders from control panel if your're using a Windows platform)
