Hi @Frankgore
Do not lose the hope, maybe there are some files with vault data you need on your hard drive. 
As you can see on the screenshot, the list of recovered files with Recuva all of them contain the vault data, but there are only 2 classic .ldb files.

But for now stop downloading/installing anything on your hard drive!
You will need to set an external hard drive as the default save location:

I’m writing an explanation what to do next.
In the meantime, download AstroGrep and Recuva (on your external drive!)
