Avia page builder does no load on a specific page

Hi,

I recently moved my site to a new server and posted some new stuff in the blog.
then i realized the imported tables did not have a primary key and auto increment enabled, i fixed that manually and my last post stopped working in the avia page builder…
i tried copying all the content from database to a “Text area” in a new post, first it loaded correctly and avia page builder was refreshed with all the visual help… then it stopped loading again
when i click edit on that specific page the page builder is stuck on loading…
here’s the address to the page : http://www.kamancomputer.com/persian-pdf-kindle/
