If you're using a LAN, I presume you have a router right? Or not? Do you connect normally using UPnP or using port forwarding? If manual port forwarding then you'll most likely have to re-do it! If UPnP, check your network settings on your computer & make sure UPnP is still enabled on your system. This 'might' help: Connection problems? Check here first! It might also be worth deleting your BS preferences whilst BearShare is closed (make a note of the settings 1st.) Then go back & reset the connection settings. The previous server no. may have been recorded in your BS prefs.
