Hi Roymc,
Go to the Limewire section of the forum, then go to "Connection Problems". Have a look through the stickys. If this is no help, do a "search" (top right, between FAQ & Home), describing your problem in general terms. If you have no joy this way, post in the connection problems section & remember to include any relevant info: O/S, L/W version, Java version, Modem/router brand & model, where you're connecting from, any firewalls, connection type ie modem, cable etc. Sure you'll find some help here!!
