I am having the same issues as everyone else and had none of the extensions that were required to be removed installed.
DWCS4 does not open correctly so I am unable to disable memento etc.
I also deleted the file cache.
Has a solution been found?
I am currently in the process of uninstalling all WA extentions -
When this extension was installed, there was a file that was replaced... not sure what file that was, but I'm thinking that be have been what caused this...
I am using Windoews Vista currently...
Thank you for any help with this.
