Problems with downgrade to 3.5.2 from 3.6

Devin,
Reinstalling did you indicated us. (Ref: “Update your theme files via FTP” on Vimeo)
Other words, because many operational problems, We decided to WP downgrade from 3.6 to 3.5.2

Our actual versions are:
WordPress: v3.5.2
Enfold: v.2.0.1

After doing this the site looks almost normally.

The new problem is that at the Admin Panel we can´t see the contents normally.
When We open the pages to edit their content in the “Avia Layout Builder”, texts are not displayed in “Visual” tab (this is the problem to fix). But in “Text” mode they can be seen OK (HTML code).
We need to be displayed properly in “Visual” mode.

Do you recommend to do to fix this?

Adrian.
