Can you re-create the old databases using an import? I mostly use phpmyadmin for that stuff.

I was able to do that with my beehive database, but I lost my wordpress database.  Not a big deal but it was 10 years of blog posts.  I don't think humanity will recover if they can't read my insightful posts!

Is tha data lost or just hidden? Maybe Wordpress can help recover it? Check their Help? I used Wordpress for a business website, but I know nowt about what you'd have to try to do.
