Rekordbox 5.0 opens but no main window

Hello,

I've done a fresh install of 5.0.  It installs fine, opens but the main window does not open.  I can see the icon in my dock and the toolbar up top.  Also, to close I can only force quit.  I'm on OS Sierra 10.12.6.  I don't have any of my usb devices plugged in, just a charger on my MBP.

Repaired all permissions.  Renamed .edb files.  Even tried to install and run 4.1 and same thing happens.  I'm at my wits end. HELP!
