One thing I liked was the notification that I had to uninstall Digital File Pro and Universal Email and reinstall Form Builder or else there may be issues.
After uninstalling all 3 I restarted Dreamweaver (CS5) as I normally do to recreate the cache which I had deleted, again a normal process for me when I am uninstalling your extensions, and I had reports of a few files that were missing, see screenshots below.
Reinstalling CSS Form Builder solved these issues but I thought it was worth pointing up as the shared files should not be removed if they are still needed by other extensions.
These are the WA extensions I have installed currently in CS5 as I am still doing most of my production work in CS4 I use CS5 for playing !

I had to make the last image a link as you have restricted each post to 4 images only.
