Tversity not Discovered by Xbox

Please advise,
I installed Tversity 2.3 pro on win 7 x64.
I removed previously configured Media center on Xbox 360 and removed extender from PC.
stopped media player network sharing service and reboot xbox360.
The tversity media server is not recognized by the xbox.
I followed the FAQ media server is available through browser and media streaming seems to be functioning on a LAN PC.
Steel in Xbox media player I go to source Computer and get - "No computers found."
What am I doing wrong?

I have the same problem. Will not detect it on a hard wired connection.
