Thanks for writing in.
1) We are unable to look at the draft, we need to be able to login to you site so we can take a look. Can you be able to give us a login credential in a secure note to your site?
2) I would recommend you to backup your site before updating or try updating first in your staging site. Here's a link that might help you with it https://theme.co/apex/forum/t/setup-updating-your-themes-and-plugins/62.
3) The pro theme is the upgraded version of x. It has the header and footer builder which x doesn't have. Visit this link for more information on the pro theme https://theme.co/pro/.
Have a great day!
