Lost Page Builder Editor — Page Changed to Text Editor

My Home page is constructed in SiteOrigin Page Builder. To try to fix the problem of the home page opening below the navigation menu, I put two WordPress text widgets at the top of the Home page containing the same content as the SiteOrigin Editor widgets–and the page has reverted to Text!! The Page Builder editor has disappeared and the Visual editor seems inactcive. Disaster. What can I do to get the Page Builder Editor back? I cannot edit anything in text. :(

Thanks!
