Anyone else having problems with it? I don't have a router. No firewalls running. When I do the connection test it will pass (after changing the default UDP port) 1 time and fail the next. When I disable UPnP, the connection test doesn't work at all. That's another thing. I thought the patch only supported router UPnP and not OS UPnP.
When I try from my dad's computer(which is the server in our 2 PC, crossover cable connected LAN) that's running XP, WinMX works fine.
