We don't need your trolling on this forum thank you. We don't need your temperament thanks. Go tell your mother then. And also tell her how impolite your posting on a public forum was. We don't need ultimatums & don't care less whether you use LimeWire or any other gnutella program. That's up to you. This is a forum & we don't appreciate your type when we help on this forum for free in our own spare time.

Most high speed modems have nat firewalls. To overcome it, enable UPnP on it or else forward a port: Connection problems? Check here first! (click on link)

We wouldn't recommend anybody getting pro if they can't connect.
