Still line break disfunction

Hi i am working with the Vantage Theme, a site origin page builder and the visual editor widget.
Everything worked fine until i updated the Visual Editor Plugin yesterday.

Since then my line breaks at the frontend do not work anymore.
It looks just fine in the editor, but at the frontend all paragraphs are somehow deleted an it shows the text as one block.

I’m using 4.0.1 WordPress Version, 1.2 Vantage Version and 2.2.1 Black Studio TinyMCE Widget.

I need help really quickly. Is there a way to use an older TinyMCE version again to make it work?

According to the posts, this is a well known issue. What can i do?

Thank you for your help
