I'm new around here but I do know about this. SP2 turns on the Windows Firewall and that is blocking a couple of ports that you need. The solution is provided in the javahmo FAQ (item #15):
1. Windows Security Center -> Windows Firewall -> Exceptions -> Add Port
Set port number 2190 and select UDP protocol
2. Windows Security Center -> Windows Firewall -> Exceptions -> Add Port
Set port number 8081 and select TCP protocol
Now that I have mine running I guess I installed the wrong app. Reading around here I find that Galleon is the way to go. Oh well!
