Total CMS blog posts no longer showing

I have created a new site, had loaded 10 blog posts and everything was working fine. Due to an SSL certificate issue I had to erase all the data on my server.

I thought it would be as simple as re-publishing all my RW files and then copying my CMS data folder called vblog (my CMS ID and folder with the .cms blog files) into the CMS-data but that is not working. There are no posts to be found. I can’t even create a new blog anymore and start again (I can log into admin, but nothing saves). Any ideas what went wrong/how to fix? Perhaps I am missing something in my cms-data directory (see image below)?

Thanks for your help!
