BeTheme Issue

I finished building my new website with new photos and content. I set up my woo commerce and products successfully. But I suddenly lost my betheme folder and all my site contents from my directory. I contacted DreamHost, and they had yet to work out the backups. They said to get you guys for support.

I reinstalled the theme from scratch and did a database restore, and still no luck. All I got is just my menus, but the contents are not what I rewrote.

I got a bunch of these errors too.
