upgrade theme: 2.1.1.1 disappeared layout from the dashboard

Thanks to Alex for this beautiful theme. it’s really fantastic and we are learning to use it. We have a problem: When we update the theme from the last version (2.1.1.1) from the dashboard disappears the overall layout, but what remains internal to individual posts and pages. It’s a problem that others have had? Ii’s there any way to solve it?
Thanks for the help
