WP update & tinyMCE/WP-edit

After updating to new WP version, some of my visual editor buttons disappeared. Discovered i had to get the plugin for WP_edit, which supposedly takes the place of TinyMCE, which is not supported in the upgrade. Did that, and reset everything, got my visual editing icons back (some of them anyway.) then, i noticed that my previous posts, when in editing mode were all screwed up. None of the images were aligned properly. IT was that way on the last several posts i checked. They seem to appear on the site properly, but in the editing screen they are totally screwed, and there is no edit button on each image to open it and realign it–not that i would do that with every freaking image in every freaking post. {{My question is, is there a way to get the edit page to show things as they are again, in the post? I won’t be able to edit any posts without redoing the whole thing again, otherwise.}}

This is precisely why i put off updating WP each time they have a new one–i spend days or weeks trying to get everythign working again.
