Can't connect
 

When I open LimeWire Pro it just says 'starting connection', and doesn't connect.

It was fine last week.

The only thing I've changed is I now have installed a wireless network in my house with Comcast. Before the weekend I was piggy-backing someone's network.

Any ideas?

Thanks!

Wireless will have a NAT protection which acts like a firewall. If UPnP is not working well or doesn't have UPnP, then you may need to port forward the device for LW. :)
