Error Message On DW Startup

I deleted all of my previously installed extensions the installed the latest version of eCart, Design Extender and Data Bridge. In that order and now I get this message.... Unable to find file WA_Mento.htm in Configuration/Floaters directory. The floater will not be shown.

I had the exact same thing. I even tried to put the files there from a Time Machine backup and that didn't work. I just reinstalled them again and it seemed to resolve the problem.

Wait... Actually what I done was install one, open Dreamweaver and activate and then on to the next one. Seemed to work fine after that.

any time you get an error message regarding floater window, you can correct it by resetting the workspace layout.

Go to Window -> Workspace Layouts -> Reset '<Your Layout Name>'

it happens if you have a floater window for one of the extensions docked to an open panel, then uninstall the extension.

I have tried to reset my workspace and I am still getting this error message?
