Hi Wesley,
Maybe you've checked this, but often rat not starting is a symptom of no 
multicast available or a firewall blocking multicast.

You could try unicast only and see if it helps by: turning off audio in 
the menu before going to a venue, then going to a venue and switching to 
unicast (assuming there is a bridge available), and finally turning on 
audio again.  If this unicast method works, then multicast connectivity is 
likely the problem -- although I'm not sure if that helps test firewall 
issues or not.
