I presume you mean LPE. On Vista or later, it is very important to set java to run as administrator. If you search for the java.exe file and then right-click it and choose Run as Administrator. I suspect this will help greatly with your connection problem. It might sound odd, but does seem to make a huge difference in ability to connect using LW5 versions at least. Might be worth doing the same with the LW shortcut.

If that did not help, then check the options to try here http://www.gnutellaforums.com/connec...t-connect.html
