I tried everything in your new post and I am still having the same problem. I don't know what the problem is. I deleted the preference folder, uninstalled LW and Java and reinstalled both from the links given in the post and still it is not working. It begins the setup wizard to let me make new preferences, but it closes after I choose the save folder. I think I am going to have to give up on LW and use another gnutella. Thank you for all your help. I will continue to check back to see if there are updates or new fixes to my problem. I really like LW-its the best that I have used, but I can't use it if it won't open.
