I have W7 64bit as well.

Since updating to 2014 internet security, my UPNP severs have died as well. (Servio, PS3 Media Center) as well as SPlashtop desktop streamer and Logmein.

They all functioned 100% working, BEFORE the upgrade. Turning off the firewall or punching holes in it for those apps do nothing.

I havent found a work around yet. :frowning:
