Rekordbox don´t read harddrive..

Hallo my software (Rekordbox) did "freeze" and I couldn´t get it working. My harddrive was in the USB slot but I couldn´t disconnect it properly as Rekordbox has "locked" it. In the end I had to reeboot the PC and now the software says my library is "broken" and ask me if I want to delete it. As I answer No the program don´t read the hard drive....
How do I get it working again?

I need it for this weekend !!
Best regards Mats

Hey GOMF,

Sorry for not getting to you in time - were you able to repair the drive and recover your library?
