1. 1st make sure your firewall is properly configured to allow LW full access, & ensure UPnP is enabled for your modem/router; see Connection problems? Check here first! (click on link)

BTW if you run a spyware utility shuch as pestpatrol, then either get a better one or put LW on the exemption list.

2. Uninstall Java using your Add/Remove programs control panel. Then install Java 1.5 using the "Offline" installer version. Delete your LW preferences folder. See how to do these things here Fixes for Limewire - click on link (see steps 1-3)

3. If still not work, delete the LW prefs folder again, then downld the "Offline" LW installer from here & reinstall http://www.limewire.com/english/content/download.shtml
