I can’t edit any pictures

I recently downloaded Windows Essentials and successfully edited many pictures, however, since the original day, I cannot do so anymore. When I click on a photo, in photo gallery, it gives me the upper task bar with edit on it, but in no longer takes to the page that lets that happen. In addition, the icon on the taskbar on the desktop no longer functions properly (it won't open). I have run a fix it under the uninstall, I have reinstalled it, still no luck. I have Windows 8. Thanks for the help.
