Need help, Trakter reverted back to default settings

So I opened Traktor to just mess around play some tunes tonight, and for some reason it has reverted back to it's original install settings. None of my playlists, controllers settings, view preferences and so on are available any more.

Any help would be appreciated on this as that's a lot of time I put into organizing my playlists and setting my controllers.

Did you do a backup of the collection file mate?

If I did I wouldn't be freaking out

Just don't understand why it would do that all of a sudden.
