Data Base Gone

Well I lost my database in the rekordbox.

My laptop was crashing while using rekordbox, so I created a new user just to use rekordbox, with less programs running in the background (windows).

So logged in with this user, openned rekordbox and there wasn´t file of my database.

So tried to move again my database and puff... everything was gone...

I mean all my files are there, but rekodbox doesn't find them all!

I have my database on a pendrive.

What should I do??

Can I recover my database either from HD or pendrive?
