I have followed through videos and all the post here that I thought might apply and found nothing.
My issue is that when I try to edit anything with the default Optin Popup 1 There is nothing in the preview windows. If I Ctrl A in the window and paste in the dreamweaver or something I get the preview. I also don't have the toolbar across the top. I have cleared cookies, uninstalled with all files etc, and re-installed with no success.
