Hope this helps Stardock:
With 8.09 installed, Directory Opus will not launch any more and going back to 8.06 did not help that.
When I unload WB and then launch Directory Opus, it launches fine. Then I can launch WB and until I reboot my machine, Directory Opus keeps launching fine.
So WB is preventing some subsistems of DO from launching, but once lanched, WB does not bother DO any more.
