Try the beta version, 4.1.9 or 4.1.10 I think it's up to. See here: http://www.gnutellaforums.com/showth...threadid=29811 Also it's a good idea to keep your Java up to date: http://www.java.com/en/download/windows_automatic.jsp for 1.4 or version 1.5 can be found here: http://java.sun.com/j2se/1.5.0/download.jsp Tell us how you go. Good luck. There is reason behind my madness for suggesting the beta. This series of betas have been very reliable & very, very good & have got a lot of people out of similar probs.
