M - We have no experience running our Pro Beta alongside the YDS of old. It would be my recommendation that you Add/Remove the Pro Beta - do not save settings when prompted. Then remove YDS in the same manner. I'd recommend a reboot and then a reinstall of the Pro Beta.
I can't guarantee this will work but its the most likely series of steps to take.
