I am having this same problem when trying to make a website. I go to edit the elements of the webpage template I have saved in "My Documents"...and no matter what element I try and edit, only the "Revert", "Cancel" and "Designs" buttons are enabled. The Save button cannot be selected (i.e. greyed out). I have used the search function to no avail to find a solution (people have had this problem for a while and it was never answered sufficiently as far as I can tell)...

What is the fix? I've uninstalled and reinstalled and still it's not working properly.
