Library missing!!!

Hi, I recently exported my whole rekordbox library to an external hard drive, which didn't take nearly as long as I though it might have (around twenty minutes for nearly 100gb).

I am now in China, and I have opened rekordbox, and my whole collection is missing! 

How can I restore it to what it was previously? All of my tracks are still there in a folder called "tunes", which is where they ares stored on my laptop, but all of the cue points are gone and none of them have been analysed. I haven't deleted anything from rekordbox. Please tell me there is a way to do a back up of some sort! I don't have the hard drive, although I will have it when I get my decks shipped over here, eventually...
