If your listening port changes then just change it back

Also you say cableconnection. Doesn't that mean that you get connected through a router or modem ? You might need to portforward or turn on UPnP in the router

Have you changed any hardware lately ?

In limewire go to tools>options>firewall config and tell us what in checked (UPnP, Portforward or Nothing)

Also go to tools>options>bugreports and press view example bugreport then copy paste it in a reply here (use Ctrl+a and Ctrl+c since rightclicking doesn't work in limewire to get those options)

this is the bug report and i havent changed any hardware and i have maual port forward on

don't you have a router/modem that you connect through ?

If you do have a router then you need to set up portforwarding and get a static IP on your computer

www.portforward.com

BTW a static IP would be a good idea even if you don't have a router
