I'm having the exact same problem ... but with just ONE of the "slaves"
I have de-installed and re-installed after deleting all of the Stardock and Multiplicity firewall rules and then reinstalling from scratch after a clean reboot.
The Stardock rules reappear after installation but NONE of the Multiplicity rules reappear on the inbound rulesets.
The only way I can get things to work is to disable the firewall for the Private Scope (which I don't like entirely). I really don't want to manually enter the rules if I don't need to.
Any recommendations as to how I can specifically get those to get reinstantiated? Also - running the exact same installer and ONE gives me "audio" options and the machine that I'm having problems with does not.
Thanks for any guidance.
