Sunbelt Personal Firewall 4

I’m using the Sunbelt Personal Firewall 4 and can’t get it to NOT black firefly.

The firewall is set up to ask me for each application what it may access and what not. This has been working fine for years and 100s of apps on my PC, but not for firefly. As soon as the firewall is turned on, my SoundBridge still “sees” firefly on the network but cannot connect to it. As soon as I disable the firewall, all works fine. Of course I don’t wonna run my PC w/o a firewall.

The curious thing is, that in case of firefly the firewall doesn’t even ask me stuff like “is firefly allowed to access the local network”. It’s like it doesn’t even notice firefly’s presence (doesn’t show up in the list of apps) and therefore I cannot allow it to run as a server.
