Problem again: Macrophone

I can’t reply to this thread:
With 3.8.65951.477 the problem is back again and I can’t configure the firewall so that the program works again.
I’m connected to the same LAN. I tried for testing TCP, IP, UDP, ICMP in and out for all addresses as a global rule. I allowed full connection for the Macrophone client. No avail. I can’t get it to work again. Somehow Comodo firewall is still blocking the app. Please help!
