Rekordbox 2.0.3 doesn't start-up after crash

I've got 2x CDJ2000 connected through LAN with Rekordbox 2.0.3 on a MacBook 2,4 GHz Core 2 Duo 2 GB SDRAM OS 10.6.8

Frequently Rekordbox crashes (after loading a song or when I press the hot cues on my CDJ to quick), then I just shut down the program and start it up again.

But with te new version 2.0.3 it doesn't start up after crashing. The only thing that works is to restart my whole computer. And that's not something you want during a performance. Does anyone have the same problem and is there a solution?
