Rekordbox 4.08 Crash

When I plug my usb in and open rekordbox, it gets stuck at  0% importing histories and then when i cancel out, a new box comes up and asks if I want to sync with my tags, but after I cancel out the whole application just freezes and I have to force quit every time. Can anyone help me out here? This was working fine on 4.07 version before, I don't know what is wrong with my usb or rekordbox for that matter.
