TV no longer can find DLNA

Gotta Panasonic Viera ST30 TV last month and downloaded and installed the Mezzmo 13 days ago (says I have 2 days left before the trial ends when I open Mezzmo). Worked pretty well right away.
Now today all of a sudden I get a "DLNA server not found" message on the TV when I go to the DLNA menu.
When I open Mezzmo on my laptop & go to Media Server Settings I see under Media Server Status that Server is Stopped.
So then when I try to Start Media Server & enter my password, I get a "The Mezzmo media server could not be registered on your computer" error message.
Have tried a bunch of times to make sure I've entered the password correctly but same thing every time.
Suggestions? Thanks.

Did you install any software recently, such as an antivirus or anything security-related? One possibility is that new software could be blocking Mezzmo from registering successfully.

Also, please check this thread for services that need to be running: http://forum.conceiva.com/showthread...rver-to-launch

In addition to that, please check that the "Netlogon" service is also running.
